Document Summary
Physiology/metabolism: uid and electrolyte balance, acid-base balance, energy, transportation (lipoproteins, blood clotting. Dri: depends on weight and stage of growth, 0. 8g per kilo of body weight, minimum is 10% of total calories, athletes may need slightly more. Essential amino acids: phenylalanine, valine, tryptophan, threonine, isoleucine, methionine, histidine, leucine, lysine. The amine group links with the acidic end of the next amino acid. Amino acids with an electrically charged side chains are attracted to water. Amino acids with neutral side chains are repelled by water: they seek each other. Protein structure and function are disrupted by a variety of things: heat, acid, alcohol, base, salts. Carried to the liver: used by the liver or released into the blood to be taken up by other cells. Cells can then use the amino acids to: make their proteins for their own use, make proteins that are released into the lymph or blood for other uses.
