Cov qauv tertiary ntawm cov protein yog hais txog tag nrho peb-dimensional kev npaj ntawm nws cov polypeptide saw nyob rau hauv qhov chaw. Nws yog feem ntau stabilized los ntawm sab nraud polar hydrophilic hydrogen thiab ionic bond kev sib cuam tshuam, thiab kev sib cuam tshuam hauv hydrophobic ntawm nonpolar amino acid side chains (Fig. 4-7).

Kuj tseem paub yog, ionic bonds stabilizes tertiary lug li cas?

Kev sib cuam tshuam uas tuav Tertiary Structure Salt Bridges: Protein fold kom zoo them cov saw hlau yog feem ntau nyob ib sab rau negatively them sab chains. Tus choj ntsev los yog ionic daim ntawv cog lus nruab nrab ntawm cov pab pawg them nqi pab ruaj khov tus tertiary qauv.

Tsis tas li ntawd, cov ntawv cog lus tshuaj dab tsi stabilize cov qauv sib txawv hauv thawj theem nrab tertiary thiab quaternary qauv? Raws li nrog disulfide txuas hniav, cov hydrogen daim ntawv cog lus tuaj yeem nqa ob feem ntawm cov saw hlau uas nyob deb deb ntawm qhov sib lawv liag. Cov choj ntsev, kev sib cuam tshuam ionic ntawm qhov chaw zoo thiab qhov tsis zoo ntawm cov amino acid sab chains, kuj pab tau. ruaj khov tus tertiary qauv ntawm ib qho protein.

Nyob rau hauv txoj kev no, theem twg ntawm cov qauv protein yog ruaj khov los ntawm hydrogen bonds?

Tertiary Structure Muaj ntau hom kev sib cog lus thiab lub zog uas tuav cov protein nyob hauv nws tertiary qauv . Hydrogen bonding nyob rau hauv polypeptide saw thiab nruab nrab ntawm cov amino acid pawg "R" pab kom stabilize protein qauv los ntawm tuav cov protein nyob rau hauv cov duab tsim los ntawm hydrophobic kev sib tshuam.

Cov ntawv cog lus dab tsi yog nyob rau hauv tertiary qauv?

Cov qauv tertiary ntawm cov protein muaj xws li txoj kev polypeptide yog tsim los ntawm complex molecular duab. Qhov no yog tshwm sim los ntawm R-pab pawg sib cuam tshuam xws li ionic thiab hydrogen bonds , disulphide choj, thiab hydrophobic & hydrophilic kev sib tshuam.
