Ho cheka le ho monya protheine 'meleng ho etsoa ka li-amino acid: joalo ka karolo ea pele ea limatlafatsi' meleng, protheine e na le karolo e totobetseng phepong ea lijo, empa e ke ke ea sebelisoa ka kotloloho 'meleng. E sebelisoa ka ho fetoha limolek'hule tse nyane tsa amino acid.

2. bapala karolo ea tekano ea naetrojene: ha boleng le palo ea protheine lijong tsa letsatsi le letsatsi li loketse, naetrojene e kenngoang e lekana le naetrojene e ntšitsoeng mantleng, moroto le letlalo, e bitsoang palo e felletseng ea naetrojene. Ebile, ke teka-tekano lipakeng tsa tsoelo-pele e tsoelang pele le ho bola ha protheine le amino acid. Kamohelo ea protheine ea letsatsi le letsatsi ea batho ba tloaelehileng e lokela ho bolokoa ka har'a mofuta o itseng. Ha ho kenngoa ha lijo ka tšohanyetso ho eketseha kapa ho fokotseha, 'mele o ntse o ka laola metabolism ea protheine ho boloka botsitso ba naetrojene. Ho kenella ha protheine e fetelletseng, ho feta bokhoni ba 'mele ba ho laola, mokhoa oa ho leka-lekana o tla senyeha. Haeba u sa je liprotheine ho hang, protheine ea lisele 'meleng oa hau e ntse e tla senyeha, mme tekanyetso e mpe ea naetrojene e tla tsoelapele ho hlaha. Ha o sa nke mehato ya ho lokisa ka nako, lesole la mmele le tla shwa qetellong.

Phetoho ho tsoekere kapa mafura: a-keto acid e hlahisoang ke katabolism ea amino acid e kopantsoe tseleng ea metabolism kapa mafura a nang le litšobotsi tse fapaneng. a-keto acid e ka hlophisoa bocha hore e be liasiti tse ncha tsa amino, kapa ea fetoloa tsoekere kapa mafura, kapa ea kenya potoloho ea tri-carboxy ho kopanya le ho bola ho CO2 le H2O, le ho lokolla matla.

Kenya letsoho ho theheng li-enzyme, lihormone le livithamini tse ling: mofuta oa lik'hemik'hale oa li-enzyme ke protheine (amino acid molek'hule), joalo ka amylase, pepsin, cholinesterase, carbonic anhydrase, transaminase, jj. lihormone ke liprotheine kapa lihlahisoa tsa tsona, joalo ka kholo ea "hormone", "thyroid" e susumetsang "hormone", "adrenaline" "insulin", "enterotropin" joalo-joalo. Li-vithamine tse ling li fetoloa ho tloha ho amino acid kapa li kopantsoe le liprotheine. Li-enzyme, lihormone le livithamini li bapala karolo ea bohlokoa haholo ho laoleng mesebetsi ea mmele le ho thusa metabolism.
