1.Ukucolwa kokutya kunye nokufunxwa kweprotein emzimbeni kwenziwa ngee-amino acid: njengesixhobo sokuqala somzimba emzimbeni, iprotein inendima ebonakalayo ekutyeni kokutya, kodwa ayinakusetyenziswa ngqo emzimbeni. Isetyenziswa ngokuguqula iiamolekyuli ezincinci zeamino acid.
2.Dlala indima yokulingana kwe-nitrogen: xa umgangatho kunye nenani leprotein ekudleni kwemihla ngemihla kufanelekile, inani le-nitrogen efakiweyo lilingana nenani le-nitrogen ekhutshwe kwilindle, umchamo kunye nolusu, ekuthiwa yibhalansi iyonke yenitrogen. Ngapha koko, kukulingana phakathi kokudibanisa okuqhubekayo kunye nokubola kweprotein kunye neeamino acid. Ukutya kweprotein kwemihla ngemihla kwabantu abaqhelekileyo kufuneka kugcinwe kuluhlu oluthile. Xa ukutya ukutya kunyuka ngequbuliso okanye kuncipha, umzimba usenokulawula imetabolism yeprotheni ukugcina ibhalansi ye-nitrogen. Ukufakwa kweprotein egqithileyo, ngaphaya komzimba wokulawula, indlela yokulinganisa iya kutshatyalaliswa. Ukuba awutyi protein, iprotein yomzimba wakho isaza kubola, kwaye ibhalansi ye-nitrogen engeyiyo iya kuqhubeka ukwenzeka. Ukuba ngaba awuthathi manyathelo okulungisa kwangexesha, esi sifo siza kuthi ekugqibeleni sife.
3.Uguquko kwiswekile okanye kumanqatha: i-keto acid eveliswe yicatabolism yeeamino acid icolwa kwimetabolism yendlela yeswekile okanye inqatha eneempawu ezahlukeneyo. I-keto acid inokuphinda yenziwe kwakhona kwii-amino acid ezintsha, okanye iguqulwe ibe siswekile okanye amanqatha, okanye ingene kumjikelo we-carboxy ukuya kwi-oxidize kwaye ibole ibe yi-CO2 kunye ne-H2O, kwaye ikhulule amandla.
4. Thatha inxaxheba ekwenziweni kwee-enzyme, iihomoni, kunye nezinye iivithamini: ubume bemichiza ye-enzymes yiprotein (ukwenziwa kweemolekyuli ze-amino acid), ezinje nge-amylase, i-pepsin, i-cholinesterase, i-anhydrase ye-carbonic, i-transaminase, njl. iihomoni ziiprotein okanye ezinye eziphuma kuzo, ezinje ngehomoni yokukhula, idlala lengqula elikhuthaza idlala, iadrenaline, insulin, enterotropin njalo njalo. Ezinye iivithamini ziguqulwa ukusuka kwii-amino acid okanye zidityaniswe neeproteni. Ii-enzyme, iihormoni, kunye neevithamini zidlala indima ebaluleke kakhulu kulawulo lwemisebenzi yomzimba kunye nokukhuthaza imetabolism.
