Kedu ihe bụ peptide?

Peptide na-ezo aka n'ụdị ngwakọta nke usoro ihe omimi ya dị n'etiti amino acid na protein, Ọ nwere ụdị amino asịd 20 dị n'ụdị dị iche iche na nhazi dị iche iche, site na dipeptides ruo n'usoro ahịrị dị mgbagwoju anya ma ọ bụ polypeptides okirikiri.Peptide ọ bụla nwere usoro pụrụ iche nke ya, yana usoro nke peptides dị iche iche dabere na ọrụ nke ha.Peptide nwere akara ọdịnaya n'ime ahụ dị ndụ, mana o nwere ọrụ physiological pụrụ iche.N'ime ha, peptides nwere ike ịhazi organism na-arụ ọrụ physiological nke na-akpọ peptide na-arụ ọrụ ma ọ bụ peptide na-arụ ọrụ biologically.Na mbido afọ 20^thnarị afọ, ihe ịga nke ọma nke kemịkalụ synthesize dipeptide na-egosi ọdịdị nke sayensị peptide.
