Ngegama le protein Iimolekyuli ezenziwe zii-amino acid ziyaziwa, ezidityaniswa luhlobo lwebhondi eyaziwa njengeepeptide bond. Iiproteni zenza malunga nesiqingatha sobunzima obomileyo bethishu (kunye ne-20% yobunzima bomzimba womntu), kwaye akukho nkqubo yebhayiloji ingazibandakanyi.

Ukubunjwa kwezi molekyuli ikhabhoni, i-hydrogen, ioksijini kunye ne-nitrogen. Ukulandelelana kunye nokulungiswa kwee-amino acid ngaphakathi kweprotein kuxhomekeke kwikhowudi yemfuzo yomntu, oko kukuthi, iDNA.

Nguwuphi umsebenzi abawenzayo?

Iiproteni zinomsebenzi obalulekileyo ekukhuleni, kwaye ikakhulu ikhuthazwa ngumxholo wenitrojeni ongafumaneki kuzo naziphi na ezinye iimolekyuli ezibandakanyiweyo ngokutya: iikhabhohayidrethi kwaye i amafutha.

Ngokungafaniyo nezi zimbini, i protein Abanawo umsebenzi wokugcina amandla, kodwa banendima ebalulekileyo ekuhlanganiseni nasekulondolozeni ezinye izicubu okanye izinto zomzimba ezinjengeejusi zesisu, ihemoglobin, iivithamini kunye nezinye ii-enzymes. Ngokufanayo, bayanceda thwala iigesi ezahlukeneyo ngaphakathi egazini, kunye nokusebenza njengesixhobo sokumothusa.

Phakathi kwe imisebenzi proteinKwelinye icala, ziya kubonelela ngee-amino acid ezifanelekileyo zokwenza izicwili, kunye nokusebenza njenge Izinto zokuguqula izinto eziphilayo ukukhawulezisa isantya se iimpendulo zamachiza imetabolism. Okokugqibela, kunokuthiwa iiproteni zisebenza ngendlela yokhuselo, kuba ii-antibodies ziiprotein zokhuselo zendalo ngokuchasene nosulelo okanye iiarhente zangaphandle.

Iipropati

Ngokumalunga neempawu zeeproteni, kunokuthiwa uzinzo Yeyona ibaluleke kakhulu kuba iiproteni kufuneka zizinze kwindawo ezigcinwe kuyo okanye apho zikhulisa khona ukusebenza kwazo, ngendlela yokongeza ubomi bazo ixesha elide kangangoko kunokwenzeka ukuthintela ukuvela kwezithintelo emzimbeni.

Kwelinye icala, iiproteni zine ubushushu kunye ne-pH ekufuneka igcinwe ukuze kuqinisekiswe uzinzo, kungoko kusithiwa ipropathi yesibini esisiseko yile ukunyibilika.

Ezinye iipropathi ezincinci ezinje Ukucaciswa, IpH buffer wave umthamo we-electrolytic Baqhelekile nakweli didi leemolekyuli.

Ukwahlulahlula

Olona luhlu luqhelekileyo lweeproteni lwenziwa ngokwendlela yemichiza yazo, phakathi iiprotheni ezilula evelisa kuphela iiamino acid xa hydrolyzed; i iialbins kwaye Iiglobulin ukuba inyibilika emanzini kwaye inyibilikise izisombululo; i izidlakela kwaye prolanins ezinyibilikayo ngaphakathi iiasidi; i iialbinoid ezingenakunyibilika emanzini; i iiproteni ezidibeneyo equlethe iinxalenye ezingezizo ezomzimba kunye proteinezivela kwezinye eziyimveliso ye-hydrolysis.

Ukubaluleka kokutya

Umthombo ophambili weprotein emzimbeni kukutya. Ukubaluleka kokubandakanya iiproteni ekudleni kugxininisa ngokukodwa kubantwana abakwixesha lokukhula kunye nakwabasetyhini abakhulelweyo, abafuna ukuveliswa kweeseli ezintsha.

Xa abantu besitya iziqhamo imifuno okanye inyama Bahlala bebandakanya isixa esikhulu seeproteni ngenkqubo eyaziwa ngokuba kukwetyiswa kweprotein, equlathe ukubola kwemveliso ide iguqulwe iiamino acid ezilula, kwaye emva koko uzihlanganise zibe ziiproteni zomzimba, kwinkqubo eyaziwa njenge iprotheni synthesis. Kuphela kusemva koku kokuba zibandakanyiwe emzimbeni.

Imizekelo yeeproteni

Ukutya okuphezulu kweprotein

Ingakukhonza:

• Imizekelo yeeCarbohydrate
• Imizekelo yeLipids (Amafutha)
• Imizekelo yeeTrace Elements (kunye nomsebenzi wazo)
