Kev solubility ntawm cov protein nyob hauv dej nyob ntawm 3D duab ntawm nwsFeem ntau globular proteins yog soluble, thaum cov fibers tsis yog. Denaturation hloov cov qauv 3D kom cov protein tsis yog globular ntxiv lawm. Qhov no tau ua nrog cov khoom ntawm cov amino acids hauv cov protein.
Puas proteins dej soluble Yog los tsis yog?
Proteins tuaj yeem muab faib ua ob pawg: fibrous, uas zoo li tsis muaj dej nyob hauv dej, thiab globular, uas ntau dua soluble hauv dej. Cov protein yuav muaj txog li plaub theem ntawm cov qauv.
Vim li cas cov proteins tsis soluble hauv dej?
Kev piav qhia: Fibrous proteins tsis yaj hauv dej vim qhov sib txawv ntawm polarity Raws li kev cai lij choj tshuaj, "zoo li dissolves nyiam". Txij li thaum dej yog polar, thiab saum npoo ntawm fibrous proteins yog them nyob rau hauv non-polar amino acids, nws tsis yaj mus rau hauv aqueous tov.
YPuas yog cov proteins soluble hauv dej ntshiab?
Yav dhau los tsis muaj txoj hauv kev dav los solubilize lawv thiab yog li lawv cov khoom siv tseem tsis tau paub. Kuj ceeb tias, peb tsis ntev los no tau pom tias tag nrho cov proteins insoluble hauv peb lub chaw kuaj mob, uas muaj ntau yam sib txawv, tuaj yeem solubilized hauv dej ntshiab.
