A na-ekewa protein n'ime klas atọ, nke jikọtara ya na ihe ndị ọzọ dị na ya: protein globular, protein fibrous, na protein membrane. Ihe fọrọ nke nta ka ọ bụrụ protein globular niile na-edozi ma ọtụtụ bụ enzymes. Protein fibrous na-abụkarị ihe owuwu, dị ka collagen, isi ihe dị na anụ ahụ na-ejikọta, ma ọ bụ keratin, protein protein nke ntutu na mbọ. Protein Membrane na-abụkarị ndị na-anabata ma ọ bụ na-enye ọwa maka polar ma ọ bụ na-akwụ ụgwọ molecules gafere na cell membrane. A na-akpọ ihe pụrụ iche nke njikọ hydrogen intramolecular n'ime protein, nke a na-echebe nke ọma site na mwakpo mmiri ma si otú a na-akwalite nkwụsị nke onwe ha, bụ dehydrons. Ajụjụ: Olee ụdị protein na-adịkarị mgbe niile?
