Li-amino acid tsa bohlokoa: Tsena ke li-amino acid tseo 'mele oa motho (kapa liphoofolo tse ling tse nang le lesapo la mokokotlo) o ke keng oa khona ho iketsetsa kapa tseo sekhahla sa tsona sa motsoako se leng hole le ho fihlela litlhoko tsa 'mele' me se tlameha ho fanoa ke lijo tse kantle. Tlhokahalo ea li-amino acid tsa bohlokoa bakeng sa batho ba baholo ke hoo e ka bang 20% ho isa ho 37% ea tlhoko ea protheine. Ho na le mefuta e 8, 'me mesebetsi ea bona ke e latelang:
Lysine: E khothalletsa tsoelo-pele ea boko, ke karolo ea sebete le gallbladder, e khothalletsa metabolism ea mafura, e laola pineal gland, mammary gland, corpus luteum le ovary, 'me e thibela ho senyeha ha sele;
Tryptophan: E khothalletsa tlhahiso ea lero la gastric le lero la pancreatic;
Phenylalanine: E kenya letsoho ho feliseng tahlehelo ea tšebetso ea liphio le senya;
Methionine: E kenya letsoho ho hlophisoeng ha hemoglobin, lisele le serum, 'me e na le mosebetsi oa ho khothaletsa spleen, pancreas le lymph;
Threonine: E na le mosebetsi oa ho fetola li-amino acid tse itseng ho finyella ho leka-lekana;
Isoleucine: E kenya letsoho taolong le metabolism ea thymus, spleen le pituitary gland;
Leucine: E leka-lekanya isoleucine;
Valine: E sebetsa ho corpus luteum, mammary gland le ovary. Semi-li-amino acid tse hlokahalang ka maemo a itseng: Li-amino acid tseo 'mele oa motho o ka li kopanyang empa hangata li sa khone ho khotsofatsa litlhoko tse tloaelehileng li bitsoa semi-ea bohlokoa kapa ea bohlokoa ka maemo. Tsena ke haholo-holo arginine le histidine, e leng li-amino acid tsa bohlokoa nakong ea kholo ea bongoana. Tlhokahalo ea 'mele oa motho ea li-amino acid tsa bohlokoa e fokotseha ha lilemo li ntse li fokotseha, ka ho fokotseha ho hoholo ho batho ba baholo ha ho bapisoa le masea. Mesebetsi ea bona ke e latelang:
Arginine: Arginine le deoxycholic acid metsoako (minoxaline) ke lithethefatsi tse sebetsang bakeng sa ho phekola syphilis, jaundice ea kokoana-hloko, joalo-joalo.
Histidine: E ka sebelisoa e le reagent ea biochemical le moemeli oa meriana, hape e sebelisoa ho phekola lefu la pelo, phokolo ea mali, ramatiki ea ramatiki, joalo-joalo.
-li-amino acid tseo e seng tsa bohlokoa: Tsena ke li-amino acid tseo batho (kapa liphoofolo tse ling tse phelang lesapo la mokokotlo) ba ka li kopanyang ho tsoa ho li-precursor tse bonolo 'me ha ho hlokahale hore ba li fumane lijong. Mehlala e kenyelletsa glycine le alanine.
