Lub quaternary qauv ntawm cov protein yog kev sib koom ua ke ntawm ntau cov protein chains lossis subunits rau hauv kev sib koom ua ke. Txhua lub subunits muaj nws tus kheej thawj, theem nrab, thiab tertiary qauv . Cov subunits yog tuav ua ke los ntawm hydrogen bonds thiab van der Waals rog ntawm nonpolar sab chains.

Nyob rau hauv no hais txog, yuav ua li cas yog lub quaternary qauv tuav ua ke?

Quaternary qauv yog tuav ua ke los ntawm noncovalent bonds ntawm complementary nto hydrophobic thiab hydrophilic cheeb tsam ntawm lub polypeptide subunits. Tsis tas li ntawd, acidic thiab yooj yim sab chains tuaj yeem tsim kev sib txuas ntsev.

puas quaternary qauv muaj covalent bonds? quaternary qauv piav txog kev sib cuam tshuam, los ntawm kev qaug zog daim ntawv cog lus , ntawm polypeptide sub-units. covalent bonds . Hauv qhov sib piv, lwm pab pawg hais tias muaj protein ntau quaternary qauv yog tias nws muaj tsawg kawg yog ob txoj kev ywj pheej uas tau tuav ua ke los ntawm cov tsis- covalent bonds.

Ntxiv mus, hom ntawv cog lus twg yog tsim nyob rau hauv lub quaternary qauv ntawm cov protein?

Quaternary qauv: Protein yog hais tias nyob rau hauv quaternary qauv yog hais tias lawv muaj ob los yog ntau tshaj polypeptide chains koom ua ke los ntawm cov rog uas tsis yog. covalent bond . Lub zog uas stabilize cov qauv no hydrogen daim ntawv cog lus thiab electrostatic bond.

Dab tsi yog quaternary qauv hauv biology?

Protein quaternary qauv yog tus naj npawb thiab kev npaj ntawm ntau folded protein subunits nyob rau hauv ib tug multi-subunit complex. Nws suav nrog cov koom haum los ntawm qhov yooj yim dimers mus rau homooligomers loj thiab cov complexes nrog cov lus piav qhia lossis cov lej sib txawv ntawm cov subunits.
