Biochemistry BCH 303 20222023 Dr Mansour Gatasheh Biochemistry Department Science College King Saud University Proteins are made up of large numbers of amino acids linked . Interactions. June 18, 2015. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. Proteins & Amino Acids. CHAPTER 6: PROTEINS & AMINO ACIDS. At the end of this chapter, you should be able to:. Describe the structure of proteins and amino acids and explain their role in health and disease. Interactions. June 6, 2017. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. Proteins account for more than 50% of the dry mass of most cells. Protein functions include structural support, storage, transport, cellular communications, movement, and defense against foreign substances. Describe the structure and functions of protein. Explain how the body uses protein. Discuss the quality and quantity of protein necessary in the diet. Give examples of complementary proteins. Learning Objectives. A nutrient found in all living things. It contains nitrogen and is responsible for the formation, maintenance, and repair of the body’s tissues/ It can also be used for energy. CHNO. Amino acids . 4. calories per gram. . The main function of protein is to . build and repair body tissues. .. If carbohydrates and fat are not available, your body will use protein. Is this a good thing? . You must eat protein . Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods. Proteins are polymers of amino acids produced by living cells in all forms of life.. A large number of proteins exist with diverse functions, sizes, shapes and structures but each is composed of essential and non-essential amino acids in varying numbers and sequences.. for . life.. . The importance of proteins was recognized by chemists in the early 19th century, including Swedish chemist . Jöns. Jacob Berzelius. , who in 1838 coined the term . protein. , a word derived from the Greek . Protein . is a very important nutrient. It makes up most of our body cells, tissues and fluids. .. Protein . Deficiency. -Leads to Kwashiorkor in children Happens mostly in impoverished countries where there is a lack of protein rich foods. . depends on the balance between the rates of synthesis and. catabolism or loss. However, also important is the relative. distribution between the intravascular and extravascular. compartments, as the concentration depends on the. Cell Bio Ch 5- 10. Sattvik Basarkod.
