Denaturation, hauv biology, txheej txheem hloov kho cov qauv molecular ntawm cov protein… Cov proteins uas tau hloov pauv muaj qhov xoob, ntau dua random qauv; feem ntau yog insoluble. Denaturation tuaj yeem coj los ntawm ntau txoj hauv kev-xws li, los ntawm cua sov, los ntawm kev kho nrog alkali, kua qaub, urea, los yog detergents, thiab los ntawm kev tshee tshee.
YYuav ua li cas thiaj muaj protein ntau?
Proteins yog denatured los ntawm kho nrog alkaline lossis acid, oxidizing lossis txo cov neeg ua haujlwm, thiab qee cov kuab tshuaj organic. Txaus siab ntawm cov neeg ua haujlwm denaturing yog cov uas cuam tshuam rau cov qauv theem nrab thiab theem nrab yam tsis muaj kev cuam tshuam rau lub hauv paus qauv.
txhais li cas rau cov protein kom denatured thiab nws tshwm sim li cas?
Protein denaturation tshwm sim thaum ib qho protein poob nws cov quaternary, tertiary, thiab lwm yam qauvQhov tseem ceeb, cov protein yuav nthuav tawm thiab tsis ua haujlwm. … Proteins ua denatured vim qee yam kev ntxhov siab sab nraud, xws li raug cov kua qaub, cov hauv paus, cov ntsev inorganic, cov kuab tshuaj, los yog cua sov.
txhais tau li cas rau cov protein enzyme kom denatured?
Denaturation koom nrog kev rhuav tshem ntawm ntau qhov tsis muaj zog H bonds nyob rau hauv ib qho enzyme, uas yog lub luag haujlwm rau cov qauv txiav txim siab ntawm cov enzyme. Feem ntau cov enzymes poob lawv cov dej num ib zaug denatured, vim hais tias substrate tsis tuaj yeem khi rau qhov chaw nquag.
piv txwv ntawm protein denaturation yog dab tsi?
Cov piv txwv zoo tshaj
Thaum zaub mov siav, qee qhov ntawm nws cov proteins ua tsis zoo. Qhov no yog vim li cas cov qe boiled ua tawv thiab cov nqaij siav yuav khov. Ib qho piv txwv classic ntawm denaturing hauv cov protein yog los ntawm qe dawb, uas yog qe albumins loj hauv dej. … Tib qhov kev hloov pauv tuaj yeem cuam tshuam nrog cov tshuaj denaturing.
