Ama-protein ayimthombo oyinhloko yama-amino acids emzimbeni, okwakuthiwa umele ukwakhiwa kwemisipha. Kodwa-ke, amaprotheni aphezulu nekhwalithi aphakeme akuyona nje ukukhula kwemisipha yomdlali, kodwa nempilo yakhe. Wonke umuntu okungenani wayefuna ukuthola imisipha, wafunda izincwadi eziningi ngamaprotheni. Manje kukhona ukungqubuzana okuningi nokuxoxisana ngezinzuzo kanye nokulimaza kwamaphrotheni amaningi, okuyinto amaprotheni angcono. Ukucabanga ngokulimaza noma okuwusizo kwamaprotheni akuyona into enengqondo, wonke umuntu uyazikhethela yena. Amaprotheni athandwa kakhulu manje ase-whey amaprotheni nama-proteinine ase-casein. Kulesi sihloko, sizobuka ukuthi i-casein iyini nokuthi isebenza kanjani.
Casein yi-protein esemqoka etholakala ebisi. Eqinisweni, njengamanye amaprotheni ayenayo, i-casein yenzelwe ukwandisa ubukhulu be-muscle futhi kusize ekushiseni amafutha amaningi.
Iprotheni ye-Casein ibhekisela kuma-protein amaningi. Isici salolu phrotheni sinciphisa kancane, okuqinisekisa ukuphuma okuqhubekayo kwama-amino acids emzimbeni kuze kube amahora angu-8. I-Casein ekudleni iyatholakala ebisi kanye neziqhamo zayo (i-kefir, ushizi, i-cottage shiese). Ngeshwa, asikwazi ukuthola amaprotheni amaningi njengoba umdlali adinga kule mikhiqizo, ngakho-ke kuphakanyiswa ukusebenzisa izithako zamaphrotheni.
I-Micellar casein
I-casein yemvelo etholakala ukuhlunga, ngaphandle kokwelapha okushisa nokomakhemikhali. Lokhu kusho ukuthi zonke izakhiwo zalo zihlala zingashintshi, ngakho-ke lokhu kungcono kakhulu amaprotheni.
Amaprotheni anamanzi
Uhlobo olunye lwamaprotheni (casein amaprotheni, whey amaprotheni, amaprotheni amaqanda, amaprotheni we-soy) anezici zalo siqu. Isibonelo, i-whey amaprotheni igcwele ama-amino acids e-BCAA (lawo amino acid abalulekile akhuthaza ukukhuthazela), unezinga eliphezulu lokuhlanza futhi ngokushesha unikeza imisipha nge-amino acid, ngakho-ke kuhle ukuyisebenzisa ngokushesha ngaphambi kokuqeqesha. Kanti, amaprotheni anesisindo anciphisa izinga le-cholesterol egazini futhi ewusizo ukungahambisani nemikhiqizo yobisi. I-protein ye-egg ine-digestibility engcono kakhulu. Iprotheni ye-Casein, njengoba sishilo ekuqaleni, yenza izinsizwa zibe ne-amino acids ende.
Kwasungulwa amaprotheni enyimbinkimbi (ingxube yamaprotheni ahlukene) azosiza ukuhlunga ama-amino acid ngesikhathi esifushane ngemuva kokuphatha, futhi uqhubeke nokudla imisipha eminingi nge-amino acids ngenxa yamaprotheni abambe kancane.
Iprotheyini enomqondo omuhle ngoba ihlanganisa izimfanelo ezinhle zazo zonke amaprotheni futhi ithambekele ekuphutheni kwabanye. Kuzofanelana bobabili abafuna ukuthola imisipha yomzimba, futhi uma "ukomisa" (sebenzisa ukukhululeka) komzimba. Sebenzisa le phrotheni ebusuku ukunikeza ama-amino acids ama-muscle amahora angu-6-8, ngoba lesi yisikhathi esiphumelele kakhulu sokukhula komzimba.
Kusukela ekuhlulekeni kwamaprotheni anzima, kungase kuphawulwe ukuthi esimweni sokuphendula okweqile kwezinye izinhlobo zamaprotheni,
Ukungathembeki ku-casein
Kubonakala kubantu abanokungahambisani nohlobo lwezinyosi ezihlukahlukene, okuholela ekunqothulweni kwepheshana lomzimba. Ngakho-ke, esinye sezibonakaliso eziqhakazile zokungabekezelelani kwe-casein yi-stool evulekile. Kodwa-ke, kunezinye izimpawu, njengokuthunga, ukukhwehlela, impumu egijimayo, ngezinye izikhathi izilonda ezinomzimba emzimbeni.
