Proteins yog tsim los ntawm cov amino acids. Tag nrho cov amino acids muaj cov qauv zoo sib xws, tab sis txawv ntawm lawv cov saw hlau. Cov saw hlau no muaj cov khoom sib txawv, qee qhov yog hydrophobic (tsis yog dej soluble) thaum lwm tus yog hydrophylic (dej soluble). … Txoj kev no ua kom ruaj khov, dej soluble protein yog tsim.
Vim li cas cov protein 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.
Yuav ua li cas protein yog soluble hauv dej piv txwv?
Hloov pauv, globular proteins yog soluble hauv dej. Piv txwv li, albuminsyog cov dej-soluble proteins uas muab cov piv txwv paub txog qhov tshwm sim thaum cov protein poob nws cov qauv theem nrab thiab qib theem, txheej txheem hu ua denaturation.
YPuas yog cov proteins soluble hauv dej ntshiab?
Tshwj xeeb, tsis ntev los no peb tau pom tias tag nrho cov proteins uas tsis tau soluble hauv peb chav kuaj, uas muaj ntau yam sib txawv, tuaj yeem solubilized hauv dej ntshiab.
Puas yog cov proteins hydrophobic lossis hydrophilic?
Proteins, ua los ntawm cov amino acids, yog siv rau ntau lub hom phiaj sib txawv hauv cell. Lub cell yog ib qho aqueous (dej-filled) ib puag ncig. Qee cov amino acids muaj polar (hydrophilic) sab chains thaumLwm tus muaj tsis-polar (hydrophobic) sab chains.
