Cofactors waxay noqon karaan kuwo aan dabiici ahayn (tusaale ahaan, ion birta iyo kooxaha birta iyo baaruudda) ama xeryahooda dabiiciga ah (tusaale ahaan, flavin iyo heme). Cofactors waxay u adeegaan ujeedooyin badan; tusaale ahaan, ion birta waxay gacan ka geysan karaan xasilinta noocyada nucleophilic ee goobta firfircoon. Cofactors Organic waxay noqon karaan coenzymes, oo laga sii daayo goobta firfircoon ee enzyme inta lagu jiro falcelinta, ama kooxaha prosthetic, oo si adag ugu xiran enzyme. Kooxaha prosthetic Organic waxay noqon karaan covalently (tusaale ahaan, biotin enzymes sida carboxylase).
