Tus txheej txheem ntawm kev hloov cov puab ntawm a protein ntau kom lub luag haujlwm poob yog hu ua denaturation. Cov protein yog yooj yim denatured los ntawm tshav kub. Thaum twg protein ntau molecules yog boiled lawv cov khoom hloov.

Ib yam li ntawd, koj tuaj yeem nug, nws hu li cas thaum cov protein poob nws cov duab?

Denaturation thiab Protein Folding. Denaturation yog txheej txheem uas proteins poob lawv puab thiab, yog li ntawd, lawv txoj haujlwm vim yog kev hloov pauv hauv pH lossis kub.

Ib tug kuj yuav nug, nws hu ua dab tsi thaum lub molecule hloov cov duab? Nyob rau hauv biochemistry, ib tug conformational hloov yog a hloov hauv puab ntawm macromolecule, feem ntau induced los ntawm ib puag ncig yam. Nws ua tau hloov nws puab nyob rau hauv teb rau kev hloov nyob rau hauv nws ib puag ncig lossis lwm yam; txhua qhov ua tau puab yog hu ua kev sib haum xeeb, thiab kev hloov ntawm lawv yog hu ua ib tug conformational hloov.

Ntxiv mus, yuav ua li cas yog tias cov duab ntawm cov protein hloov pauv?

Protein muaj nuj nqi ncaj qha ntsig txog cov qauv ntawm qhov ntawd protein ntau . A cov protein tshwj xeeb puab txiav txim nws txoj haujlwm. Yog peb-dimensional qauv ntawm lub protein hloov vim muaj kev hloov pauv hauv cov qauv ntawm cov amino acids, cov protein ntau ua denatured thiab tsis ua nws txoj haujlwm raws li qhov xav tau.

Cov tshuaj ntxuav tes puas tuaj yeem hloov cov duab ntawm cov protein?

A cov protein 3-D qauv yog ib feem tsim los ntawm hydrophobic thiab hydrophylic kev cuam tshuam rau nws tus kheej, lub tshuaj ntxuav tes hloov qhov no tus kheej bonding nrog tshuaj ntxuav tes - amino acid sib txuas. Tsis tas li ntawd, tshuaj ntxuav tes yog ntsev thiab rhuav tshem cov kev sib raug zoo thiab tsis zoo ntawm 3-D puab ib yam nkaus.
