Proteins: chemical structure of protein, proteins are working and structural molecules made from c, h, o, and n atoms, composed of amino acids (aa) which have the same chemical back bone. Central carbon atom, amine group (nh3), acid group (cooh: distinctive chemical side chain attached to center carbon (r) Shape, size, charge, behavior: 20 amino acids in body, 9 of these are essential to have in diet to maintain them. Fibrous (connective tissue: shape determined by amino acid, primary, some composed of interlocked strands: quarternary structure. Active transfer of substances in and out of cells to maintain composition of body fluids via concentration gradients: acid-base balance: normal metabolic processes produce caids and basis which influence blood ph, buffer. Proteins in blood absorb acids: blood clotting: specialized liver blood proteins respond to an injury and clot blood. Protein forms net around opening, prevents flowing out of blood vessels: energy and glucose: ideally not.
