PROTEINS – (DR. TRAISH) Introduction to Proteins - Proteins are abundant and functionally diverse molecules - They participate in cell regulation at all levels - They share a common structural 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. proteins of milk, meat and eggs.. Milk composition. Deficient in iron and vitamin C. Milk proteins. Total protein content in milk – 2.9 – 3.5%. Two major types of milk protein. Caseins (80%). Whey proteins: (20%). 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. Chromatin is made of repeating units of nucleosomes, which consist of 146 base pairs of DNA wrapped around an octamer of four core . histone proteins (H3, H4, H2A and H2B). Introduction. Histones are a special group of proteins found in the nuclei of eukaryotic cells responsible for DNA folding and chromatin formation.. 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.. Objectives:. Know the basic terminology related to fats and proteins. . Know the classifications of fats and proteins.. Basic terminology related to fats and proteins. Fat. denotes an ester composed of glycerol (tri-hydric alcohol) and three fatty acids of (triacylglycerol or triglycerides).. Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids.. Biocompatibility and Cellular Overview Part 2. Outline . Biocompatibility.
