Research into Enzymes – For Biology Rennin Rennet, substance found in the gastric juices of young milk-drinking mammals. Rennet contains a milk-coagulating enzyme, called rennin or chymosin, the active principle of rennet preparations used in making cheese and junket. Rennet extracts are commercially prepared from the inner lining of the fourth stomach of calves. Enzymes Enzymes are large proteins that speed up chemical reactions. In their globular structure, one or more polypeptide chains
The Effect of Temperature on the Activity of Rennin in Milk Aim: To find out what effect different temperatures have on the enzyme, rennin, in milk. Introduction An enzyme is a biological catalyst. It speeds up a reaction by lowering the activation energy required to start the reaction. It speeds up a reaction, but remains unchanged unless certain limiting factors are introduced. It is composed of polymers of amino acids. An enzyme has an optimum pH and temperature. When an enzyme
Varying Concentration of Rennin and Its Effect on the Goagulation Time of Milk Scientific Knowledge Enzymes Enzymes are large molecules, which are protein in nature. They are biological catalysts that speed up chemical reactions in the body. They operate by a "lock and key" method. The Enzyme has a certain "lock" (active site) that only a specified substrates "key" will fit into. Enzyme action Rennin A proteolytic enzyme that speeds up the coagulation of milk. It is usually
Rennin – A Proteolytic Enzyme Major Discussion: Role of rennin in helping young mammals digest milk Role of rennin as an industrial catalyst to make cheese Proteolytic Enzyme: Any group enzymes that catalyze the hydrolytic degradation of proteins or polypeptides to smaller amino acids polymer is called proteolytic enzyme. Rennin is a proteolytic enzyme made by chief cells in the stomach. Rennin also known as “Chymosin”. Rennin enzyme plays an important role in helping young mammal digest milk
rennet, my partner and I decided upon the first option. We made this decision as we felt it would be valuable to our scientific knowledge if we had a better understanding of how different temperatures can effect the behaviour of an enzyme, such as Rennin, which is also known as Chymosin. Our scientific knowledge tells us that enzymes work most efficiently at specific temperatures, and this experiment helps us to discover exactly which temperatures they are. It is important to remember that the
curds formed, I concluded that specimens Ca and Cb also cannot perform the process of proteolysis. My conclusion is supported by the fact that there was no clearing of the medium. I have also determine that neither of my organisms can make the enzymes rennin, proteolytic or even proteases. I know my specimens cannot produce proteases due to the fact that there was no blue coloring in the tubes which means that the byproduct Ammonia was not produced to increase the pH. Since neither of my specimens can
the development of cardiovascular diseases including stroke and may also have a role in the development of vascular cognitive impairment and vascular dementia [1, 2]. Angiotensin I-converting enzyme (EC 3.4.15.1; ACE) plays an important role in the rennin-angiotensin system and it is a carboxyl-terminal dipeptidyl exopeptidase that catalyzes the conversion of angiotensin I to angiotensin II [3-6]. ACE converts an inactive form of decapeptide, angiotensin I, to a potent vasoconstrictor, octapeptide
Hypertension is a condition, where the force of blood pumping through body is high enough for it to cause internal damage. High blood pressure is determined by measuring the force of the blood against the blood in your arteries and the amount of resistance with the arteries. Blood pressure is measured by sphygmomanometer, this device measures the systolic and diastolic pressures in the arteries. The systolic is the top the number in blood pressure which should be around 120. While the diastolic is
Scientist have discovered in 2012 that cheese goes as far back as 7,500 years. This was discovered in Poland, 34 pottery sieves that were tested by scientist to find the purpose of them. Cheese is linguistically significant because we use it in our everyday language and it is a part of our everyday lives. Some metaphors that we use in the United States are “Say cheese”, “Cheesy”, and lastly “who cut the cheese?” These are the most commonly used cheese metaphors/sayings in America. Cheese was discovered
Heart failure (HF) is a complex clinical pathological syndrome characterised by symptom of shortness of breath , fatigue and the sign of rales on chest ascultation and peripheral pitting oedema also termed as sign of congestion. It is caused by the structural and functional diffect of the heart(1) . It is initally characterised by the dysfunction of the levt ventricle which lead to impairing the filling functin of the ventricles or unable to produce enough contractility of the left ventricle
According to Statistics SA hypertension is one of the leading non communicable diseases in South Africa1. It is a major risk factor for the development of various cardiovascular diseases and thus has been shown to contribute to heart failure and stroke. There is a high prevalence of undiagnosed and untreated hypertension in South Africa1. In order to improve therapeutic interventions it is essential to understand all the mechanisms that are associated with this disorder. Therefore recent studies
Common Factors Contributing to Food Poisoning Food poisoning can be defined as: “An acute (arising suddenly and of short duration) gastroenteritis caused by the ingestion of food.” – www.food.gov.uk Food poisoning is characterized by the following symptoms: · Abdominal Pain · Diarrhoea · With or without vomiting · With or without fever Major problems with food poisoning occur in the very young, the very elderly and those with otherwise reduced immunological defences
The Cambridge dictionary defines microorganisms as living thing that on its own cannot be seen without a microscope. Also known as microbes, they are categorised into 6 main types this includes: Bacteria, Viruses, Algae, Archaea, Protozoa and Fungi. In this piece of writing I will explore the main benefits of microorganism to Man in the economy and society as well as its consequences. Microorganisms are very important in the environment and its ecosystems, however they are also very beneficial to
Casein plastic, or ‘milk plastic’, has been used in the Americas for decades, due to its low production costs and accessibility. Casein is defined as, “A white, tasteless, odorless protein precipitated from milk by rennin” (“Casein” 1). and “a slow digesting protein that plays a large role in preventing muscle breakdown” (“Casein Protein“ 1). Not only is casein an important protein that all mammals need to survive, but this vital protein has also been very important throughout recent American and
Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body’s ability to provide adequate oxygen to be utilized in cellular respiration. With an increase
Cardiovascular Disease in the African American Community Causes, Preventions, and Treatments Cardiovascular disease (CVD) refers to the dysfunctional conditions of the heart, arteries, and veins that supply oxygen to vital life- sustaining areas of the body like the brain, the heart itself and other vital organs. Since the term cardiovascular disease refers to any dysfunction of the cardiovascular system there are many different diseases in the cardiovascular category, and many of these diseases
Introduction Cheese production has been going on for many years and is a traditional art. There are many benefits of cheese nutritionally because it is versatile. Cheese can be used as a source of protein, vitamins, minerals, phosphorus, and calcium. Cheese can be a convenience food for people because it can be eaten as the main component, a dessert, a snack, a condiment or as an ingredient used to make foods. There are over five hundred types of cheese and they are continuing to study and make a
Ms. Gm, my client, lived alone in the community housing corporation. On this faithful morning my patient woke-up complaining of severe headache, fatigue, inability to sleep, dyspnea and dizziness. Following this situation she was taken to the hospital by a neighbor and while she was in the emergency department she was seen by the physician where she was diagnosed with hypertension. Hypertension is deadly and it is a silent killer, if not detected on time, it can cause severe complications to major
Chronic kidney disease (CKD) is a worldwide problem that is currently three times higher for African Americans, Hispanics, Pacific Islanders, American Indians and seniors (The National Kidney Foundation, 2013). CKD occurs when the kidneys are damaged by a pathogen or injury and they can no longer adequately maintain proper levels of regulated chemicals in the bloodstream. There are many risk associated with CKD. According to the National Kidney Foundation, two of the major risks are Chronic Renal
