izindaba

1.Ukugaywa nokumuncwa kwamaprotheni emzimbeni kufezwa ngama-amino acid: njengesakhi sokuqala somsoco emzimbeni, amaprotheni anendima esobala ekudleni kokudla, kepha ayinakusetshenziswa ngqo emzimbeni. Isetshenziswa ngokujika ibe ngama-molecule amino acid amancane.

2.dlala indima yebhalansi ye-nitrogen: lapho ikhwalithi nenani lamaprotheni ekudleni kwansuku zonke kufanelekile, inani le-nitrogen elifakiwe lilingana nenani le-nitrogen ekhishwe endle, umchamo nesikhumba, okubizwa ngokuthi ibhalansi ephelele we-nitrogen. Eqinisweni, ibhalansi phakathi kokuhlanganiswa okuqhubekayo nokubola kwamaprotheni nama-amino acid. Ukudla kwamaprotheni nsuku zonke kwabantu abajwayelekile kufanele kugcinwe ebangeni elithile. Lapho ukutholakala kokudla kukhuphuka ngokungazelelwe noma kwehla, umzimba usengalawula imetabolism yamaprotheni ukugcina ibhalansi ye-nitrogen. Ukufakwa kwamaprotheni ngokweqile, ngaphezu kwamandla omzimba wokulawula, indlela yokulinganisa izobhujiswa. Uma ungawadli nhlobo amaprotheni, amaprotheni ezicubu emzimbeni wakho asazobola, futhi ibhalansi engemihle ye-nitrogen isazoqhubeka nokuvela. Uma ungathathi izinyathelo zokulungisa ngesikhathi, i-antibody ekugcineni izofa.

3.Ukuguqulwa kube ushukela noma amafutha: i-keto acid ekhiqizwa yi-catabolism yama-amino acid ihlanganiswa endleleni yoshukela noma amafutha anezici ezahlukahlukene. i-a-keto acid ingaphinde ihlanganiswe ibe ama-amino acid amasha, noma iguqulwe ibe ushukela noma amafutha, noma ifake umjikelezo we-tri-carboxy ukwenza i-oxidize futhi ibole ibe yi-CO2 ne-H2O, futhi ikhulule amandla.

4. Bamba iqhaza ekwakheni ama-enzyme, ama-hormone, kanye namavithamini athile: isimo samakhemikhali sama-enzyme amaprotheni (ukwakheka kwe-amino acid yamangqamuzana), njenge-amylase, i-pepsin, i-cholinesterase, i-anhydrase ye-carbonic, i-transaminase, njll. Izakhi ze-nitrogen equkethe ama-hormone amaprotheni noma okuphuma kuwo, njenge-hormone yokukhula, i-hormone egqugquzela i-thyroid, i-adrenaline, i-insulin, i-enterotropin njalonjalo. Amanye amavithamini aguqulwa asuka kuma-amino acid noma ahlanganiswe namaprotheni. Ama-enzyme, ama-hormone, kanye namavithamini adlala indima ebaluleke kakhulu ekulawuleni imisebenzi yomzimba nasekuvuseleleni imetabolism.
