Document Summary

All living cells synthesize proteins: w/o protein synthesis, life wouldn"t exist, 1000s of proteins in body, highest conc. Of any nutrient (except water) in all animals. Protein solubility: proteins range from v. insoluble to v. soluble. Very soluble: plasma globulins: have large variety of funcs. Protect body, digest feed, metabolize nutrients, stimulate, defend against invading organisms. Proteins are chains of amino acids: amino acids. Contain an amino (-nh2) and a carboxyl (cooh) group. Physical and chem derived from amino acid sequence and linkages to other compounds (r groups) Dna codes for proteins: dna controls protein synthesis; this is in nucleus. Specifies order in which amino acids are linked. Amino acids are supplied in diet or result from digestive processes. Amino acid synthesis: most proteins in plants and animals composed of abt 20 amino acids. Animals need a source of these proteins to synthesize all of them.
