Protein - a kubalulekile

Protein - iklasi kwezinto eziyimfuneko ukuze ubomi zonke izinto eziphilayo. Isibakala sokuba iimolekyuli zayo baphathe isixa esikhulu se ezahlukeneyo nemisebenzi ngaphandle apho ubukho onke amaziko abahlala kwakuya akunakwenzeka.

Yintoni le nkqubo ibandakanya iiprotheni?

izinto nganye enjalo luquka inani elikhulu ngokwaneleyo inamacandelo ezincinane ekuthiwa acid. Iyonke open nje 40 Kulo mzekelo, umzimba womntu inokufumaneka-20 kuphela kubo.

acid zinokudityaniswa phantse nawuphi na umyalelo. Ukutshintsha isikhundla ubuncinane omnye kubo ithetha olukhulu izakhiwo kunye nemihlaba, nto leyo eya kuba protini. Ngenxa yoko, kukho emininzi iintlobo iiproteni ukuza kuthi ga ngoku.

Imisebenzi zeprotheyini neemolekyuli

Okwangoku, ziphuma ukuba iiproteni zidlala indima ebalulekileyo kuzo zonke izinto eziphilayo. Isibakala sokuba kwiproteni - kukho into eziphilayo esebenzayo, onako ukuba negalelo ngalinye izidumbu. Ngokwendalo, kumasebe ahlukeneyo emzimbeni kunxibelelana kwiiproteni ezahlukeneyo.

Ukuba sithethe malunga umsebenzi kwiproteni, oko kuqala kuyimfuneko ukuze umbonise ukuba iwandlale kubo arhente ezininzi ebonakalayo emzimbeni - enzyme iihomoni. Bona elawula ukutya komntu ngamnye amanqanaba ayo. imizekelo Zintle ezi iiprothini ziquka: pepsin, chymotrypsin, somatropin, vasopressin, insulin, prolactin, kunye nabanye.

Ukongeza kufanele kuqatshelwe ukuba iiproteni luqulathe imicu kwezihlunu. Ngenxa ngokweempawu ezizodwa actin kunye myosin, loo mntu, kwakunye nazo zonke izilwanyana bayakwazi ukuhamba. Inyaniso ukuba ungenwe ukhululeke. Ngenxa yokuba kulawulwa yinkqubo luvo, iifayibha kwezihlunu ukunika motion. Ngenxa yoko, neprothini - into eyenza umntu kunye nezinye izinto eziphilayo ukuhamba.

Kwakhona, kwiimeko ezithile, iiproteni lungasetyenziswa njengomthombo wamandla. Nangona kunjalo, oku kwenzeka kuphela xa umzimba lifumana imali elingonelanga carbohydrate kunye namafutha. Ngoko ke, singatsho ngokuqinisekileyo ukuba protein - into leyo, nangona ingasetyenziswa njengento amandla, kodwa angenzelwanga ukulungiselela le njongo.

Umxholo protein eneentlobo ezahlukeneyo

Ukuze uqinisekise ukuba lo mntu unikezelo ebalulekileyo kufuneka malunga 100 g protein ngosuku. Kukholelwa ukuba uninzi kwiproteni zingafumaneka ngenxa yenyama. Enyanisweni, yonke into into eyahlukileyo. iiproteni Uninzi e caviar chuma nesalmon kunye sturgeon. Ukongeza, omninzi protein equlethwe iimbotyi zesoya, ezimhlophe yomile amakhowa, neembotyi, neentlumaya nee-ertyisi.

Phezu kwayo yonke le nto, kuba kwiproteni ngabantu - le into ethe wafumana ikakhulukazi inyama, inkuku, kunye nentlanzi. Ingakumbi iiproteni izityebi ukutya ezifana tuna, inyama yenkomo, inyama yenkukhu, inyama yehagu, umvundla, Turkey kunye ham.

Into ebalulekileyo umthombo protein zezona Swiss kunye sisi Dutch. Ezinye iimveliso ezivela ngobisi kuba protein ephantsi ngokwaneleyo.

Abantu abaninzi abanomdla protein kangakanani na amaqanda. Ngoku sele siyazi ukuba inani elikhulu iiprotheni ukuba yome belinganisela. Ke amaqanda njengesiqhelo, kukho protein kakhulu inyama.
