Lub tertiary qauv ntawm ib tug protein yog peb seem ntawm cov protein. Disulfide daim ntawv cog lus, hydrogen bonds , ionic daim ntawv cog lus , thiab kev sib cuam tshuam hydrophobic tag nrho cuam tshuam rau cov duab ntawm cov protein.
Raws li, dab tsi txiav txim siab tus qauv tertiary ntawm cov protein?
Protein tertiary qauv yog qhov peb seem ntawm a protein ntau . Cov tertiary qauv yuav muaj ib txoj hlua polypeptide "caj qaum" nrog ib lossis ntau dua protein ntau theem nrab cov qauv , cov protein ntau thaj chaw. Kev sib cuam tshuam thiab kev sib raug zoo ntawm cov saw hlau sab hauv ib qho tshwj xeeb protein txiav txim nws tertiary qauv.
Tsis tas li ntawd, vim li cas cov qauv tertiary ntawm cov protein tseem ceeb? Tertiary qauv yog tseem ceeb ! Cov kev ua haujlwm ntawm cov protein (tshwj tsis yog zaub mov) nyob ntawm nws tertiary qauv . Yog tias qhov no cuam tshuam, lub protein ntau tau hais tias yog denatured [Kev Sib Tham], thiab nws poob nws txoj haujlwm. denatured enzymes poob lawv lub zog catalytic.
Nyob rau hauv kev hwm rau qhov no, dab tsi yog lub zog loj tswj tertiary protein qauv?
Lub zog loj stabilizing tus qauv tertiary yog kev sib cuam tshuam ntawm hydrophobic ntawm nonpolar sab chains hauv cov tub ntxhais ntawm cov protein. Ntxiv stabilizing rog muaj xws li electrostatic kev sib cuam tshuam ntawm ionic pawg ntawm cov nqi rov qab, hydrogen bonds ntawm polar pawg, thiab disulfide bonds.
Dab tsi amino acid stabilizes tertiary qauv ntawm cov protein?
Kev tsim ntawm cov txuas hniav disulfide los ntawm oxidation ntawm sulfhydryl pawg ntawm cysteine yog ib qho tseem ceeb ntawm stabilization ntawm protein tertiary qauv , tso cai rau qhov sib txawv ntawm cov protein ntau saw yuav tuav ua ke covalently. Tsis tas li ntawd, hydrogen bonds tuaj yeem tsim los ntawm cov pab pawg sab nraud sib txawv.

Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus

Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog qhov kev txiav txim kom raug rau cov kev cuam tshuam ntawm Calvin lub voj voog?
