Amaprotheni omuncu. Amaprotheni emikhiqizweni yobisi

Phakathi kwazo zonke izingxenye zemikhiqizo yezilwane, amaprotheni obisi abonakala ngokukhethekile. Lezi zici ziphakeme kakhulu kuneziqanda, izinhlanzi ngisho nenyama. Lokhu kuzokujabulisa abaningi. Phela, cishe abantu abane bathola amaprotheni angaphansi. Kuyafaneleka ukucabangela le nto ngokucophelela.

Kuphi amaprotheni amaningi?

Ubisi lwezinkomo ezivamile eziwumthombo omkhulu wezinhlobo eziningana zamaprotheni: i- serum - globulins nama-albin, kanye ne-sodium caseinate. Ku-100 milliliters yalomkhiqizo uqukethe 3.2 amagremu wenxenye ewusizo. Kulezi, ama-3 kuya ku-6% i-globulin, i-10 kuya kwezingu-12% i-albin, 80 kuya ku-87% i-casin. Ngenxa yalokho, kubonakala ukuthi inani lamaprotheni alinayo ngaphezu kwe-0.6 amagremu. Ngakho-ke, ubisi lonke akufanele kuthathwe njengomthombo we-albinini.

Ngokuqondene nezinye izinto, i-whey igxile emaprotheni obisi, eyenziwa nge-serum ngaphansi kwezimo zezimboni, iqukethe amaprotheni angu-90%. Faka imikhiqizo efanayo njengesizathu sokukhiqizwa kwefomula lesana, kanye nokudla kwemidlalo. Ukugxila kwamaprotheni amasondo angathengwa. Kodwa-ke, kaningi kusetshenziswe ngendlela engahlelekile ngaphandle kwemibhalo efanele noma kuphela ngokuningi.

Amaprotheni we-Whey

Amaprotheni omuncu atholakala amasondo ayalinganiswa nokubunjwa kwe-amino acid. Ngakho-ke, zingasetshenziswa njengokudla. Isimiso sokugaya ngokushesha esifakwe serum lactalbumin. Ihora emva kokusetshenziswa komkhiqizo onjalo, ama-amino acids asevele atholakale kuzo zonke izitho ezizidinga.

Ukwakhiwa kwamaprotheni we-Whey

Kuzo zonke izingxenye zokudla, lokhu kuhlanganiswa kwe-amino acid kuyisilinganiso esiseduze kakhulu kwizingxenye zomzimba wesisindo somuntu. Amaprotheni anama-whey anekhono eliphezulu le-anabolic. Ngaphezu kwalokho, le nxenye inenani elikhulu lama-amino acids ngamaketanga ahlanganisiwe. Phakathi kwabo - i-valine, i-isoleucine ne-leucine. Babizwa nangokuthi iBBCAA. Lezi zakhi zidlala indima ebalulekile ekwakheni izicubu zomzimba. Ngenxa yalokho, kwakha umbuthano ononya. I-BCAA ivuselela amaprotheni synthesis. Kodwa futhi bathatha iqhaza ekwakheni izicubu zomzimba. Vumelani, amaprotheni omsoco aphelele.

Izici zomkhiqizo

Amaprotheni kufanele afakwe ekudleni kwalabo abafuna ukusimamisa isisindo sabo. Phela, lesi sigaba siphuthumisa izinqubo ze-metabolic ezikuvumela ukuthi uphule ngokushesha amafutha angaphakathi naphakathi. Ngaphezu kwalokho, whey amaprotheni kusiza ukujwayelekile izinga amagazi lipoproteins kanye cholesterol, futhi kwandisa insulin ukuzwela.

Kuyafaneleka ukukhumbula ukuthi le ngxenye ineyinye ikhwalithi ebalulekile. Iprotheyini ye-Whey iyisidakamizwa sokulwa nokucindezeleka kunazo zonke. Yiqiniso, ungacabangi ukuthi lesi sici sinjengokudambisa futhi singavimbela ukuqala ukudumazeka ngokomzwelo. Akunjalo. Ngokusho kocwaningo, i-lactoalbumins isiza ekunciphiseni izinga le-cortisol - i-hormone yokucindezeleka eyinhloko, futhi futhi yandisa i-serotonin-i-hormone yenjabulo. Yilokho okunciphisa izinga lokucindezeleka okungenakufika ngemva kokusheshisa, ukungqubuzana, usuku olukhuni lokusebenza, ukuzikhandla ngokomzimba ngokweqile, njalonjalo. Ngamanye amazwi, whey amaprotheni angathuthukisa izinga lokuphila.

Casein

Le ngxenye ingenye yezingxenye zamaprotheni obisi. Noma kunjalo, kuthatha isikhathi esiningi ukuyigaya kunezinye izinhlobo. Yiqiniso, lokhu akusho ukuthi i-casein ngumkhiqizo osindayo. Ngaphandle kokuhlukaniswa komzimba umzimba udinga izinsiza kanye namandla. Kumele kuqashelwe ukuthi ukugaya kancane kancane kwalesi sigaba kuqinisekisa ukunikezwa kwama-amino acid egazini. Ngenxa yalokho, inani lezizinto ligcinwa ezingeni elidingekayo lamahora ayisithupha. Yingakho amaprotheni anjalo obisi yobisi awumkhiqizo omuhle kakhulu wokunakekela izingane ezinyangeni ezinhlanu.

Indlela yokuthuthukisa ukufana kwe-casein?

Lapho imikhiqizo yobisi iphenduka umuncu, lapho i- lactose (ushukela wobisi) iguqulwa ukuba ilacate (lactic acid), ama- calcium caseinate amafolda futhi ekugcineni iphenduke ibe amaprotheni mahhala. Kulesi simo, enye inqubo iyenzeka. I-calcium iyanqamuka kancane kancane kusuka ku-casein, ifakwe ku-asidi, ngaleyo ndlela yenza i-lactate, futhi igwetshiwe. Ngenxa yalokho, ukugaya ukudla kuyanda kakhulu. Amaphrotheni emikhiqizweni yobisi, isibonelo, nge-curd, kefir kanye ne-yogurt, ayithinteka kakhulu. Kulesi simo, ukudla okunjalo kunenzuzo enkulu kunobisi lwezinkomo.

Inhlanganisela yobisi amaprotheni nezinye

Amaprotheni we-Milk, okwakhiwa ngawo manje, ahlanganiswe ngokuphelele nezinye izinhlobo zamaprotheni. Lo mkhiqizo une-surplus enkulu ye-methionine, i-amino acid equkethe isulfure. Kulesi simo, kule protein ye-legumes, le nto ayanele. Imikhiqizo enjalo ayinayo i-tryptophan. Ngesikhathi semikhiqizo yobisi le nto iningi. Ngakho-ke, inhlanganisela enhle iyinhlanganisela yama-soy ne-whey amaprotheni.

Kunezinye izinhlanganisela. Ukuphelelana ngokuphelele ngamaprotheni we- milk and vegetable. Lezi zinsuku zitholakala kumazambane, amantongomane, ama-buckwheat, okusanhlamvu.

Amaqiniso Ngama-proteine We-Milk

Imikhiqizo eqinisekisiwe ne-KSB (whey protein concentrate) inenani eliyingqayizivele lezinto eziphilayo nezomsoco. Ukufakwa kokudla okunjalo ekudleni kusiza ukwandisa imisebenzi yokuzivikela yomzimba nokuphikisa kwayo emiphumeleni emibi. Lokhu kuthuthukisa kakhulu ukulinganisela kwengqondo nokusebenza.

Cishe amaphesenti angu-14 azo zonke amaprotheni ayenziwe nge-hydrolyzed. Ngamanye amazwi, asesimo sama-amino acids nama-peptide. Izingxenye ezinjalo aziphazamisi umsebenzi we-acid-forming wesisu. Lokhu akufaki ukuhlukumeza nokunye okungavamile.

Kubalulekile ukukhumbula ukuthi i-KSB iyinhlamba futhi inamathele ngokuphelele iphunga. Ngakho-ke, umkhiqizo kufanele ugcinwe endaweni eyomile ekushiseni okungenakuphakama kunama-29 ° C, futhi futhi kumswakama wesihlobo okungaphezulu kuka-65%.
