Qhov sib txawv tseem ceeb ntawm denatured thiab undenatured proteins yog tias denatured proteins tsis tuaj yeem ua nws qhov qub, qhov tsis muaj protein ntau tuaj yeem ua lawv txoj haujlwm zoo.
Proteins yog ib qho ntawm plaub yam tseem ceeb hauv cov kab mob uas muaj sia nyob, lwm qhov peb yog carbohydrates, cov rog thiab cov zaub mov. Cov protein molecule yog ib tug loj macromolecule uas muaj ib tug loj tus naj npawb ntawm rov qab units uas sawv cev rau cov monomers siv los ua cov protein molecule. Cov monomers no yog cov amino acid molecules.
Denatured Protein yog dab tsi?
Denatured protein molecules yog cov proteins uas tau poob lawv txoj haujlwm zoo vim qhov hloov pauv ntawm cov qauv protein. Thaum lub sij hawm tus txheej txheem ntawm denaturation, cov macromolecules poob lawv cov theem nrab, tertiary los yog quaternary lug uas tshwm sim nyob rau hauv lawv haiv neeg lub xeev. Qhov denaturation no tshwm sim vim yog siv qee qhov kev ntxhov siab sab nraud lossis ib yam khoom. Cov kev ntxhov siab sab nraud muaj xws li hluav taws xob, kev hloov pauv ntawm qhov kub thiab txias, hloov pH, thiab lwm yam. Cov khoom sab nraud uas tuaj yeem ua rau cov protein muaj xws li cov kua qaub, cov hauv paus muaj zog, cov kuab tshuaj organic, qee cov ntsev, thiab lwm yam.
Daim duab 01: Cov teebmeem ntawm qhov kub thiab txias ntawm Enzyme Activity
Rau cov protein molecule, cov protein folding qauv yog tus yuam sij rau nws cov kev ua tau zoo. Hauv lwm lo lus, cov proteins yuav tsum tau muab tais rau hauv txoj cai zoo thiaj li ua tau haujlwm. Hydrogen bonds ua lub luag haujlwm tseem ceeb hauv cov txheej txheem folding protein. Txawm li cas los xij, cov hydrogen bonds yog cov tshuaj tsis muaj zog uas cuam tshuam tau yooj yim los ntawm tshav kub, acidity, sib txawv ntsev ntau, thiab lwm yam. Yog li ntawd, muaj cov yam ntxwv no tuaj yeem ua rau muaj protein ntau.
Yuav ua li cas yog cov Protein Undenatured?
Undenatured proteins yog cov proteins uas ua haujlwm tau zoo uas tsis tau muaj kev cuam tshuam ntawm cov qauv. Proteins yog tsim los ntawm ntau cov amino acids; Yog li, cov no yog macromolecules. Cov kab sib txuas ntawm cov protein uas muaj cov amino acids me me yog hu ua polypeptide.
Daim duab 02: Tus Qauv Protein
Muaj plaub hom qauv loj ntawm cov protein: thawj cov qauv, cov qauv theem nrab, cov qauv tertiary thiab quaternary qauv. Feem ntau cov proteins muaj cov qauv folded uas yog 3D qauv. Cov qauv no yog lub npe hu ua cov qauv ntawm cov protein, thiab nws yog cov protein ua haujlwm zoo, kuj muaj npe raws li cov protein tsis muaj qhov tsis zoo. Feem ntau, cov qauv tertiary ntawm cov proteins thiab cov qauv quaternary yog cov qauv tseem ceeb tshaj plaws uas tshwm sim hauv cov kab mob nyob.
Qhov txawv ntawm Denatured thiab Undenatured Protein yog dab tsi?
Cov proteins uas tsis zoo thiab tsis zoo yog ob hom qauv ntawm cov protein molecules. Qhov sib txawv tseem ceeb ntawm denatured thiab undenatured proteins yog tias denatured proteins tsis tuaj yeem ua nws txoj haujlwm qub, thaum cov proteins uas tsis muaj peev xwm ua tau lawv txoj haujlwm zoo. Feem ntau lwm yam tseem ceeb uas yuav ua rau lub denaturation ntawm ib tug protein qauv yog kub, hluav taws xob, hloov nyob rau hauv pH, muaj zog acids thiab bases, thiab lwm yam.
Hauv qab infographic qhia qhov sib txawv ntawm denatured thiab undenatured protein nyob rau hauv daim ntawv tabular.
Summary – Denatured vs Undenatured Protein
Cov proteins uas tsis zoo thiab tsis zoo yog ob hom qauv ntawm cov protein molecules. Denaturation ntawm cov protein molecule tshwm sim vim muaj ntau yam xws li kev hloov pauv hauv qhov kub thiab txias thiab pH ntawm qhov nruab nrab uas cov protein nyob. Qhov sib txawv tseem ceeb ntawm denatured thiab undenatured proteins yog tias cov denatured proteins tsis tuaj yeem ua nws txoj haujlwm qub, hos cov proteins uas tsis tau muaj peev xwm ua tau lawv txoj haujlwm zoo.
