1.What are the key issues in the external and competitive environment affecting your organisation Discuss the opportunities and threats for your organisation - Essay Example he organization by applying relevant, correct strategic management theory to determine the key issues in the external and competitive environment affecting Morrison Supermarket1 as an organization. By so doing, the paper aims also to discuss the industry opportunities and threats. Strategic management aims for attainment of corporate objectives. Strategic management theory could use the models called Porter’s five forces and SWOT to determine the external and competitive environment affecting Morrison Supermarket. Before proceeding further, therefore, we have to understand the meaning of the models. SWOT stands for strength, weaknesses, opportunities and threats. As to how the models relate to each other, Porter’s five forces will dissect the facts classifying the effects of the industry forces to the profitability2 of the industry. For example, the ease or difficulty of entry, which is part of the model, assumes that the presence of entry barriers is an opportunity since less competition will allow present players to have wider area for influencing prices. SWOT includes the company’s strengths and weaknesses as opportunities and threats but we are only interested on the latter. The opportunities and threats that will be derived will be used to attain corporate objectives. As to how to attain objectives, industry opportunities must be taken advantage while industry threats must be avoided or overcome. The taking of advantage will be in the nature of the strategies that need to be formulated and implemented to attain the desired objectives of Morrison Supermarket. Strategies must be prepared in relation to industry opportunity and threats as well as company’s strengths and weaknesses. However, since strengths and weaknesses are not made part of this analysis, it must made clear that any strategy that may be may not fully consider the complete model. New entrants will find few big players, which make them concentrated, making it difficult for

Art Exhibit on Nature Essay Example for Free

Art Exhibit on Nature Essay The planet earth is the only known habitat for humankind. For millions of years, it served as the home to numerous living things such as animals, plants and people. More so, it has been a witness to many events that have shaped the course of world history. Because of this, it is suffice to say that our beloved Mother Earth has played a vital role in nourishing and sustaining the existence of humans. In return for all the benefits and nourishment that Mother Earth has provided to humans, human beings have showed their gratitude by expressing their appreciation and admiration for the beauty and splendor of nature. For centuries, human beings have captured the magnificence of the diversity and uniqueness of the environment which was shown using various art forms such as painting, sculptures, photography, architecture and many others. In line with this, throughout history, several art movements have emerged. There were the Classical, Renaissance, Baroque, Modernism and many others. The dominant and styles and themes differed in these art periods. However, there was one theme that has remained constant until the present day. This is known as landscape or nature art. This form of art is defined as the illustration of mountains, flora and fauna, bodies of water and the sky. More so, it is a celebration of the majestic beauty of nature. This trend in the art world has continued to persist throughout the ages. Aside from this, it has also evolved in terms of styles and techniques. Every part of the globe has developed their own approach on how to translate the beauty of nature into a canvas. Because of the variety in culture and tradition, nature and landscape artworks have surfaced as distinctive copies of the wonders of the environment. With this, nature had become a worldwide art phenomenon and these artworks have made nature a timeless masterpiece that will be forever treasured and recognized. On the other hand, due to changing times, the seemingly everlasting beauty of nature is apparently gradually diminishing. If before humans respected the significant role of Mother Earth in the cycle of life, nowadays, humans have abandoned their vital task of being the steward. Instead of taking care of the natural wonders of the world, humans have opted to obliterate it. This sudden change was caused by the desire to improve the ways of living of people. Initially, the intention may seem innocent and harmless but if one would look closely, traces of selfishness and greed can be uncovered. People wanted to advance the human race but at the expense of damaging the environment. Because of this, a drastic natural occurrence has been plaguing the contemporary society. This has claimed lives of many people and destroyed millions worth of properties. This phenomenon has been labeled as climate change or global warming. In the recent years, Mother Earth has been experiencing unusual changes such as the increase in temperature of the atmosphere, extinction of some animal and plant species, loss of land mass and many others. These alterations have posted an alarming threat to the existence of many living things. If humans would permit this condition to carry on, in time people would be left homeless and without any nourishment. To help intensify awareness on the present state of the environment, an art exhibit will be put up. This exhibit will showcase the nature artworks of American artist, Ansel Adams, French painter, Paul Cezanne, and a Japanese artisan named Hokusai. The objective of the exhibit is to help the viewers realize the importance and connection of nature with the existence of humans. More so, this nature-themed art exhibit will explore the various perceptions of artists on nature from different periods. It will demonstrate how people saw and appreciated the beauty of the environment during their respective eras. By incorporating artists from different continents such as North America, Europe and Asia, viewers will also be given a 360 degrees view of the world’s most beautiful places. Hopefully, after they have seen the exhibit, the viewers will have a new-found respect on the beauty and vigor of Mother Earth. Ansel Adams is an American photographer who has mastered the artistry of capturing wonderful shots of landscapes in scenic places strewn all over the United States. Aside from being an artist, he was also a dedicated environmentalist â€Å"who encouraged understanding of, and respect for, the natural environment. † Even though he initially got noticed as a noted photographer in commercial photography, he excelled in the field of landscape photography (Notablebiographies. com). The black and white landscape photographs have become Adams’ trademarks. Two of Adams most recognized photographs are the â€Å"The Tetons and Snake River, Grand Teton National Park, Wyoming† and â€Å"‘Old Faithful’ geyser, Yellowstone National Park, Wyoming† (TheHistoryPlace. com). Adams was commissioned to take these pictures for the National Park Service in 1941. The photographs were intended to be used to make the â€Å"photo mural for the Department of the Interior Building in Washington, DC. † The main theme was focused on showcasing nature â€Å"exemplified and protected in the U. S. National Parks† (U. S. National Archives and Records Administration). These two photographs have illustrated the grandiose and picturesque beauty of the mountain ranges and national parks in the US. Furthermore, he used his creativity to â€Å"preserve the wilderness and one of the first to promote photography as an art form† (TheHistoryPlace. com). Paul Cezanne is considered as one of the masters of post-Impressionism. He is also well-known for pioneering an avant-garde movement then called cubism in the late 1800s. Because of his quirkiness and modern styles, Cezanne was misunderstood by the people. But this did not discourage him to advance his creativity. He â€Å"grew out of Impressionism and eventually challenged all the conventional values of painting in the 19th century through its insistence on personal expression and on the integrity of the painting itself. † Through these innovations, he was recognized as the â€Å"father of modern painting† (Pioch). But before Cezanne ventured into cubism, he created several simple yet exquisite landscape paintings that â€Å"immortalized the Provencal countryside† in France. In his two paintings, â€Å"Etude: Paysage a Auvers† (Study: Landscape at Auvers) and â€Å"Jas de Buffan† (The Pool), Cezanne was able to depict nature as real as he can. These two oil paintings were generated in 1873 and 1876 respectively. For Cezanne, nature cannot be accurately duplicated in a canvas. He tried to link the natural and artistic worlds by showing his own perceptions about nature. In relation to this, most of his artworks are advised to be seen as a whole and not per part in order to fully appreciate their artistic essence (Pioch). Hokusai is a famous Japanese painter. Compared to the previous artists, his choice of material for painting is unconventional. Hokusai used wood as his canvas to celebrate the beauty of nature. A native of Edo, which is now called Tokyo, Hokusai is regarded as â€Å"one of the outstanding figures of the Ukiyo-e or pictures of the floating world (everyday life), school of printmaking† (Pioch). In the â€Å"The Breaking Wave Off Kanagawa or The Great Wave,† Hokusai illustrated the splendor of the sea. Since Japan is surrounded by water, this painting has become the quintessential representation of Japanese aesthetics. This seascape painting with a Japanese natural landmark, Mt. Fuji, had represented the Asian geography. More so, it showed the combination of western and eastern influences with regards to art production. Moreover, this particular Japanese art have preserved its authenticity and oriental aesthetic by â€Å"flattening the texture and using color surfaces as an element. † On the other hand, this painting also showed how nature can be so powerful which was expressed on the giant which was on the verge of devouring the people aboard the two boasts (Andreas. com).

Reflection on Self Development in Mental Health Nursing

Reflection on Self Development in Mental Health Nursing The Nurse Association (ANA) (2003) defines nursing as the promotion, protection and improvement of health and abilities, stopping of illness and injury, relief of suffering through identification, medical care and support in the care of individuals, families, societies and citizenry (Nancy, 2001 p.2).Generally nursing is liable to the society for providing quality, economical as well as improving the care rendered. Hence, nurses are responsible for their patients standard of health. The area of practice I would like to develop in this regard is mental health. The World health Organisation (WHO) (2009) defines mental health as a state of well-being where all individual notices his or her own potential, can cope with normal stressful events of life, can be fruitful and productive, and is able to contribute meaningfully to his or her society. For a person to live happily and meaningfully in life, mental health is important as well as physical health. Inadequate mental health can interfere with keeping meaningful relationships, having a sense of fulfilment in ones self, work and ability to perform in daily activities of life. Mental illness can obstruct ones interest in sleep, food and sexual contact. How we cope with life situations, the way we think and feel can be defined as mental health. By description mental health could be defined as a state of well-being which enables one to be fruitful, being able to live in peace with other people, adjusts to alteration and been able to handle difficult situations. Health conditions marked by alteration or abnormalities in mood, thinking or behaviour (or a mixture of the three) that causes discomfort or impair functioning is known as mental disorder. Giving a lot of definition without going into thorough details is difficult. One huge reason that is partly responsible for the difficulty in defining mental health, mental disorder and mental illness is the differentiation between mental and physical health which is largely pretended. Our ability to think, feel and respond is governed by our brain. The brain needs constant supply of oxygen and nutrients like any other organ in the body because it can also be damaged by thyroid issues, tumours and physical trauma. Mental health and physical health are interweaved (Linda, 2010, p.334). STRENGTHS AND WEAKNESSES ANALYSIS OF MY CURRENT KNOWLEDGE BASE ON MENTAL HEALTH My main tool as a mental health nurse is caring for the elderly living with dementia. As a mental health nurse I show compassion for the people I am dealing with by showing care towards them. Regrettably, there is still some stigma attached to mental illness. Combating this and helping the individuals and their families deal with it is the key part of my job. The danger of violence is often associated with this branch of nursing and one of the special skills required is to spot a build-up of tension and defuse it. Dealing with the behaviour and human mind is not an exact science. The job of helping people back to mental health is every bit as valuable and satisfying as caring for those with a physical illness. Showing professional compassion in my field of practice as a mental health nurse is a very important strength that I possess. For true care to take place feeling compassionate and empathetic towards a stranger is a must; a good feedback feeling is set into motion by doing this. Feelings are important in a humans life. I will say compassion is strength because it is a very important ingredient in nursing profession. Compassion is more than just showing pity or concern; and some dictionary definitions indicate that compassion is part of caring because it involves suffering with the person (Moya, 1992 p 5). As a mental health nurse, it is my duty to understand how to care for the elderly with dementia because their cognitive and affective states are conflicting. Now my experience with the elderly does not appear to me differently put myself into the private world of my patient and this is what empathy and care requires. Moya (1992, p 8) suggested that though as mortals we may find true empathy hard to practice because true empathy is only possible among archangels. My weakness on my current knowledge based on this area unfortunately is lack of Confidence which is evident in certain instances. Public speaking, presentation and demonstration of procedures to nursing assistance plague me. It is one thing to be nonchalant and laid back when speaking with your family and friends, but in a professional environment the whole mood and interpretation of things changes. It all comes down to one thing, the amount of self -esteem that i have and i am willing to exert. CLEAR STATEMENT FOR PERSONAL KNOWLEDGE Snow (1991, pp. 195-197) identifies compassion as pain, sorrow or grief for someone else. Emotions help me focus my moral actions. From my personal knowledge as a mental health nurse, compassion should be totally added in my concept of care. Furthermore the role of a Registered nurse is to improve the health and well-being of the people. My aim in focus is to strive for moral height because I have the opportunity as a nurse to give attention to the pain and suffering of my patients (Ferrel, 2005, p. 86), with a workable process in leadership and putting more compassion in practice. Putting compassion into nursing care is really not an easy task as it involves a lot of work. How this will be achieved is by involving in a compassion program for qualified nurses; going into wards that are already selected for excellence in compassion. In addition getting myself in an NHS Lothian centre for compassionate care which is also called the beacon ward where patients can be asked what we the nurses are doing right and tell us how can improve health (2008) puts it as bottling the magic formula and sharing it. The beacon ward will involve me using an all about me sheet which patients will fill when admitted. This form is not about their medical conditions; about how they will love to be addressed and who is important to them. This gives me an opportunity to look at people values and beliefs. DEVELOPING KNOWLEGDE IN THIS AREA My professional role and expectation from my clients as a mental health nurse is to win trust and establish contact with my clients. They find it difficult to gain trust and build good relationships with professionals in this field. In achieving this, competence is needed. What is competence? Spencer Spencer (1993) describe competency as the ability to realize organizational goals. It involves skills, attitudes and knowledge. These soft skills are vital in this area of practice. Developing my knowledge in mental nursing will enable me be a better nurse and gain a higher level of competency. Registered mental health nurses are regularly faced with clients who stay away from care. They involve patients with severe personality and behavioural disorders, older people living with dementia. Nursing and Midwifery Council (2002) Professional code of conducts describes situations where my professional role as a nurse is needed to be put into practice as regards competence. Throughout my year of practice I must keep my knowledge and skills up to date. Taking part in learning activities that will develop my performance and competence. In order to practice competently and professionally i must possess the knowledge, skills and abilities needed for lawful effective and safe practice without supervision. I must know the things that I am capable of doing and only accept those procedures and practice that I am competent at. If an area of practice is above my level of competence or outside my area of specialty I should call for help and supervision from a competent practitioner except otherwise. SMART CHART DETAILING HOW I WOULD ACHIEVE MY GOALS My goals, when adequately structured can be achieved in a means elaborated below using a SMART CHART. Extension (2008) stressed that SMART goals will enable one achieve relevant actions and goal; they further explained SMART is an acronym for goals that are: Specific, Measurable (Mutual, Motivated), Attainable, Relevant/Realistic, and within a specific Timeline. Clearly stated, my goals are: Improvement in the area of my level of competence as a mental health nurse Ability to win patient trust Develop my level of confidence Broaden my level of knowledge in mental nursing S My goals are limited to my area of improvement and strengths particularly related to my area of specialization which makes it specific M These goals serve as a driving force to my striving for excellence in mental health nursing A A right move in attaining or achieving these goals is by the embarking on my current programme in the University which has boosted my assurance of being a figure head in the nursing profession. R My goals are still in line with my first degree and profession hence its relevance in to my career and to the improvement of patient status. The Nursing and Midwifery Council has embarked on nurses self-development training programmes which my goals conform to. T Putting into utmost consideration my level of adaptation to the health system of the UK and my academic pursuit, my goals are already being actualized and is an on-going process of development till my career is over because learning is a continuous process and knowledge is acquired on a daily process.

Proteins Essay example -- science

Proteins Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word â€Å"proteies† or â€Å"primary†. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions are the most diverse of any family. Whether found in humans, animals, plants or in single-celled bacteria, proteins are made of units of 20 different amino acids. Proteins consist of macromolecules called polypeptides, made from monomers called amino acids. Proteins have hundreds, thousands, or sometimes even millions of these amino acids. These amino acids are made up of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. Some proteins consist of only single polypeptides. In most cases it involves two or more combined polypeptides, sometimes with other small organic molecules or metal ions. The most basic level of protein structure, called the primary structure, is the linear sequence of amino acids. Different sequences of the acids along a chain, however, affect the structure of a protein molecule in different ways. Protein’s secondary structure often contains long stretched out chains of amino acids called strands that line up together to make sheets. These are called beta strands and the sheets are called beta-pleated sheets. A protein may contain either or both alpha helices and beta pleated sheets. Alpha helices and beta pleated sheets are joined by less clear structures often grouped together under the name of coil. Some small proteins may be made of coil. Shape is also important. Proteins are coiled and twisted, giving it a unique shape. The shape depends on the sequence of the amino acids, which can be hydrophilic or hydrophobic. Those that are hydrophilic want contact with water and will be twisted to maximize contact. Those that are hydrophobic are twisted in such a way to minimize contact. Changing one amino acid in the polypeptide sequence can destroy this shape and make the protein function improperly if not at all. A very important function that proteins can serve are to act as catalysts. Enzymes are organic catalysts ma... ... cells their shape and as well as parts of the linkages that stick cells together into tissues and organs. So, the sequence of amino acids in all proteins is genetically determined by the sequence of nucleotides in cellular DNA. So basically Proteins are basic constituents in all living organisms. They are complex molecules composed of amino acid and necessary for the chemical processes that occur in living organisms. Proteins are sometimes referred to as macromolecular polypeptides because they are very large molecules and because the amino acids of which they are composed are joined by peptide bonds. The vast majority of the proteins found in living organisms are composed of only 20 different kinds of amino acids, repeated many times and strung together in a particular order. Each type of protein has its own unique sequence of amino acids. Also each protein makes every living organism different. Bibliography: 1.

Enzymes in the Dairy Industry

Cherno Okafor Aida Stefani SBI4U Octover 20th, 2012 Assignment 1: Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times, enzymes have played an important role in food production. Especially in the diary industry, some enzymes are required for the production of cheese, yogurt, and other dairy products, while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today, enzyme applications in such processing get more difficulties because of the rare occurrence and high costs.The aim of using the microbial enzymes is to achieve this problem. Five of the more common types of microbial enzymes involved in the dairy industry involve: Rennet, Proteases, Lactase, Catalase, and Lipases. Milk contains proteins, especially caseins which maintain its liquid form. Proteases are enzymes that are added to milk during the process of cheese product ion, to hydrolize caseins, like kappa caseins, which stabilizes micelle formation and thus preventing milk coagulation. On the other hand, rennet and rennin are general terms for enzymes used to coagulate milk.The Chymosin enzyme which can be obtained from animal, microbial, or vegetable sources, is responsible for up to 70% of cheese production. It is now possible to produce chymosin in genetically modified fungi. These modified microorganisms contain the gene derived from the stomach of calves that is responsible for producing chymosin. When grown in a bioreactor, they release chymosin into the medium. Afterwards, the enzyme is extracted and purified, yielding a product that is 80%-90% pure. Natural rennin contains only 4%-8% active enzyme.Chymosin produced by genetically engineered microorganisms is now used to produce cheese in many different countries. Rennet (Chymosin) has owed to an increase in demand for cheese production worldwide. Rennin acts on milk in two stages, by enzy matic and by nonenzymatic action, resulting in the coagulation of milk. In the enzymatic phase, the resultant milk becomes a gel due to the influence of calcium ions and the temperature used in the process. Many microorganisms are known to produce rennet-like proteinases, as mentioned above, which can substitute the calf rennet.Good yields of milk-clotting protease may be obtained in a medium containing 4% potato starch, 3% soybean meal, and 10% barley. During growth, lipase is secreted together with the protease. Therefore, the lipase activity has to be destroyed by reducing the pH, before the preparation can be used as cheese rennet. Protease is another notable enzyme. Cow milk contains a number of different whey proteins such as lactoglobulin and lactalbumin. The denaturing of these whey proteins, using proteases as catalysts, results in a creamier yogurt product. The denaturing of whey proteins is also essential for cheese production.In addition, proteases reduce allergic proper ties of cow milk products for infants, which produce healthier milk for them. Lactease is a glycoside hydrolase enzyme that decomposes lactose into its constituent sugars of galactose and glucose. Lactose intolerant individuals can result from insufficient production of lactase enzyme in the small intestine. Feeding lactose-containing milk to lactose-intolerant individuals can result in discomforts such as: cramps, gas, dehydration, diarrhoea in the digestive tract upon ingestion of milk products, or maybe even death.Lactase provides relief for lactose and tolerant individuals because it can be used commercially to prepare lactose-free products, particularly milk by the process of hydrolysis of the lactase into glucose and galactose. In addition, lactase enzymes can be used in preparation of ice cream to make a creamier, sweeter-tasting product and improving digestibility. Finally, this reduces sandiness due to crystallization of lactose in concentrated preparations. Also, cheese ma nufactured from hydrolyzed milk ripens more quickly than the cheese manufactured from normal milk.Another problem presented by lactose is its low solubility. This prevents the use of concentrated whey syrups in many food processes as they have an unpleasant sandy texture and are readily prone to microbiological spoilage. Adding to this problem, the disposal of such waste whey is expensive due to its high biological oxygen demand. These problems may be overcome by hydrolysis of the lactose in whey; the product being about four times as sweet, much more soluble and capable of forming concentrated, microbiologically secure, syrups.Technologically, lactose crystallizes easily which sets limits to certain processes in the dairy industry, and the use of lactase to overcome this problem has not reached its fullest potential because of the associated high costs. Moreover, the main problem associated with discharging large quantities of cheese whey is that it pollutes the environment. But, t he discharged whey could be exploited as an alternate cheap source of lactose for the production of lactic acid by fermentation. In the production of cheese, hydrogen peroxide is a potent oxidizer and toxic to cells.Catalase enzymes are used are used instead of pasteurization, when making certain cheeses such as Swiss, in order to preserve natural milk enzymes that are beneficial to the end product and flavour development of the cheese. Due to pasteurization, these enzymes would be destroyed by the high heat. Therefore, Catalase enzymes are typically added to convert to the hydrogen peroxide to water and molecular oxygen which will enhance final production. Finally, there are the lipases in the dairy industry. Lipase enzymes are primarily used to break down milk fats and give characteristic flavours to cheeses.The flavours come from the three fatty acids produced when milk fats are hydrolyzed. Hydrolysis of shorter chains of fatty acids is preferable as it results in desirable taste s of many cheeses unlike the hydrolysis of longer chains of fatty acids which could result in soapiness or no flavour at all. It is notable to mention egg products. Many industrially produced cream products used dried egg powder instead of fresh eggs. The enzymes of lipase and glucose are implemented in order to preserve egg powder and maintain its colour.These enzymes are often produced with the assistance of genetically modified microorganisms. Genetically modified microorganisms result in better yields in simply systems. Several cheese making experiments have been carried out with recombinant chymosin and the general aspects of recombinant chymosin have been dealt with. Since most of the rennet (>90%) added to cheese milk is lost in the whey, immobilization would considerably extend its catalytic life. Several rennets have been immobilized, but their deficiency as milk coagulants has been questioned.So, there is a fairly general support for the view that immobilized enzymes canno t coagulate milk properly, owning to inaccessibility of the peptide bond of K-Casein, and that the apparent coagulating activity of immobilized rennets is due to leaching of the enzyme from the support. Different types of conventional cheeses have been successfully made by using recombinant rennet on an experimental scale. No major differences have been detected between cheeses made with recombinant chymosins or natural enzymes, regarding cheese yield, texture, smell, taste, and ripening.Cheese ripening is a complex process mediated by biochemical and biophysical changes during which a bland curd is developed into a mature cheese with characteristic flavour, texture, and aroma. The desirable attributes are produced by the partial and gradual breakdown of carbohydrates, lipids, and proteins during ripening, mediated by several agents (i) residual coagulants, (ii) starter bacteria and their enzymes, (iii) nonstarter bacteria and their enzymes, (iv) indigenous milk enzymes, especially proteinases, and (v) secondary inocula with their enzymes.Proteolysis occurs in all the cheese varieties and is a prerequisite for characteristic flavour development that can be regulated by proper use of the above agents. Cheese ripening is essentially an enzymatic process which can be accelerated by augmenting activity of the key enzymes. This has the advantage of initiating more specific action for flavour development compared to use of elevated temperatures that can result in accelerating undesirable nonspecific reactions, and consequently off flavour development.Enzymes may be added to develop specific flavours in cheeses, for example lipase addition for the development of Parmesan or Blue-type cheese flavours. The pathways leading to the formation of flavour compounds are largely unknown, and therefore the use of exogenous enzymes to accelerate ripening is mostly an empirical process. Moreover, there are Proteolytic enzymes of lactic acid and bacteria in fermented milk product s.This system is composed of proteinases which initially cleaves the milk protein to peptides; peptidases which cleave the peoptides to small peptides and amino acids; and transport system responsible for cellular uptake of small peptides and amino acids. Lactic acid bacteria have a complex proteolytic system capable of converting milk casein to the free amino acids and peptides necessary for their growth. These proteinases include extracellular proteinases, endopeptidases, aminopeptidases, tripeptidases, and proline-specific peptidases, which are all serine proteases.Aminopeptidases are important for the development of flavour in fermented milk products, since they are capable of releasing single amino acid residues from oligopeptides formed by extracellular proteinase activity. Nevertheless, the other minor enzymes having limited applications in dairy processing include: glucose oxidase, catalase, superoxide dismutase, sulphydryl oxidase, lactoperoxidase, and lysozymes. Glucose ox idase and catalase are often used together in selected foods for preservation. Superoxide dismutase is an antioxidant for foods and generates H2O2, but is more effective when catalase is present.Thermally induced generation of volatile sulphydryl groups is thought to be responsible for the cooked off-flavour in ultra high temperature processed milk. Use of sulphydryl oxidase under aseptic conditions can eliminate this defect. The natural inhibitory mechanism in raw milk is due to the presence of low levels of lactoperoxidase, which can be activated by the external addition of traces of H2O2  and thiocyanate. The societal impacts of some dairy enzymes are that chymosin, a high quality enzyme, is available at an attractive price.This helps assure available of extra cheeses at a reasonable cost. Due to the lipases, there is a wide variety of flavourful, high-quality cheeses. To sum up, I think that it is amazing that there is a wide variety of alternatives of dairy products as a resu lt of these enzymes that aid the dairy processes. The lactase enzymes can now help individuals enjoy the nutritional benefits and sensory pleasure of dairy products without gastrointestinal side effects by selecting lactose-free or lactose-low dairy products or by providing commercially available lactase to dairy products in the home.It is interesting how these enzymes sustain processes that enable higher yields, more enzyme production; and higher activity, more efficient, affective, dynamic enzymes.

Common French Phrases

Common French Phrases To keep up a conversation in any foreign language, its important to familiarize yourself with common phrases and expressions. Odds are that theyll come up more often than not. In French, some of the most common phrases, like pas de problà ¨me (no problem) are similar if not identical to their English equivalent. These expressions are usually taught in class and tend to be relatively easy for students to grasp and recall. Not all common French phrases are simple.
