Protein synthesis is the process whereby proteins are produced‚ or synthesized‚ in living things according to "directions" given by DNA (deoxyribonucleic acid) and carried out by RNA (ribonucleic acid) and other proteins. As suggested earlier‚ this is an extraordinarily complex process that we do not attempt to discuss here. Following synthesis‚ proteins fold up into an essentially compact three-dimensional shape‚ which is their tertiary structure. DNA contains the instructions for a cell’s structure

PROTEIN ENERGY MALNUTRION Types include:[2] * Kwashiorkor (protein malnutrition predominant) * Marasmus (deficiency in both calorie and protein nutrition) * Marasmic Kwashiorkor (marked protein deficiency and marked calorie insufficiency signs present‚ sometimes referred to as the most severe form of malnutrition) Note that this may also be secondary to other conditions such as chronic renal disease[3] or cancer cachexia[4] in which protein energy wasting may occur.

potential sources of energy intake and expenditure and the factors that affect intake and expenditure such as basal metabolism‚ age‚ gender‚ climate and physical activity. Food is a source of energy intake as it contains carbohydrates; there main function is to store energy in the muscles. Carbs are a macronutrient and come in two different forms‚ simple which are foods like chocolate and sweets these release energy quickly‚ the other form is complex which are foods like pasta and rice they release

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are

Protein Article Research Sara Langrell December 15‚ 2011 Nutrition SCI/241 Dr. Venessa Lee Abstract: Athletes have been searching for years for a way to reduce the amount of recovery time between work outs. Based on this issue there has been quite a lot of research conducted to find out what can be done‚ if anything‚ to either reduce or eliminate recovery time. One of the theories is to increase protein intake above the daily recommended amount‚ thereby providing the body with additional

streptozotocin to the DNA molecule causes damage‚ which along a defined chain of events‚ results in the fragmentation of the DNA. Protein glycosylation may be an additional damaging factor . In the attempt to repair DNA‚ poly(ADP-ribose) polymerase (PARP) is overstimulated. This diminishes cellular NAD+‚ and subsequently ATP‚ stores the depletion of the cellular energy stores ultimately results in beta cell necrosis. Although streptozotocin also methylates proteins ‚DNA methylation is ultimately responsible

‚2010 I. Introduction Human beings require food to grow‚ reproduce‚ and maintain good health. Without food‚ our bodies could not stay warm‚ build or repair tissue‚ or maintain a heartbeat. Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fuelled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals‚ and water. Good health

High Protein Diets: Good or Bad? Lose weight while feasting on steak‚ burgers‚ cheese‚ and bacon? All without feeling hungry? What’s not to love? Meat lovers have flocked to high-protein‚ low-carb plans like Atkins‚ Zone‚ Protein Power‚ and Sugar Busters. While these diets can work‚ you need to carefully consider the risks and rewards before deciding if one is right for you. How Much Protein? Most Americans get 12%-18% of their calories from protein. With a high-protein diet‚ it can be much

DENATURATION OF PROTEINS Abstract The experiment aimed to use the concept of viscosity to study the effects of different denaturants on 1% albumin extract. An Ostwald viscometer was used to measure the flow time of 5 mL of the blank and native protein. These were then denatured by adding 1 mL of denaturant and had their flow time measured. The flow time from the blank to denatured protein is increasing. The specific viscosity and reduced viscosity
