Document Summary
20 amino acids that make up all proteins. 9 of the 20 amino acids are essential (must be ingested on a daily basis to make protein) Harry (histidine), potter (phenylalanine), is (isoleucine), learning (leucine), magic (methionine), to (threonine), thwart (tryptophan), lord (lysine), voldemort (valine) 11 of the 20 we have the capacity to synthesize. Joined together by condensation reaction (removal of water) Broken apart by hydrolysis reaction (addition of water) Two amino acids joined together to form a dipeptide. Most abundant protein in the body: collagen. Occurs in physiological system at small temperature variations. Uncoil and lose their shape - becomes nonfunctional. Only macronutrient that is digested in the stomach. Proteases break down proteins into smaller segments. Amino acids (aa) transported into intestinal cells. R group dictates which transporter the amino acids use. Specific carriers for amino acids and small peptides - takes them into enterocyte (cell of intestinal lining) Unused aa are sent to the liver via the bloodstream.
