Dab tsi yog Cov protein Ua Los ntawm? Lub tsev blocks ntawm cov proteins yog cov amino acids, uas yog cov organic me me molecules uas muaj cov alpha (central) carbon atom txuas mus rau ib pawg amino, pawg carboxyl, hydrogen atom, thiab cov khoom sib txawv hu ua cov saw hlau sab (saib hauv qab).

Ib yam li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov protein yog dab tsi?

Kev piav qhia: Muaj 20 qhov sib txawv amino acids uas ua rau cov protein. Txhua amino acid muaj cov pa roj carbon nruab nrab. Cov pa roj carbon nruab nrab yog sib koom ua ke rau pawg amine (NH2), pawg carboxyl (COOH), hydrogen atom thiab ib pawg R.

Tom qab, lo lus nug yog, dab tsi yog cov qauv protein thiab kev ua haujlwm? Cov protein quav mus rau hauv cov duab tshwj xeeb raws li qhov sib lawv liag ntawm cov amino acids hauv cov polymer, thiab cov protein ua haujlwm yog ncaj qha ntsig txog qhov tshwm sim 3D qauv . Cov protein kuj tuaj yeem cuam tshuam nrog ib leeg lossis lwm yam macromolecules hauv lub cev los tsim cov kev sib dhos nyuaj.

Tsuas yog li ntawd, 4 cov qauv protein yog dab tsi?

Ib qho protein molecule yuav muaj ib los yog ntau tshaj ntawm cov qauv protein: thawj, theem nrab, tertiary, thiab quaternary qauv

  • Cov Qauv Tseem Ceeb. Lub hauv paus ntsiab lus piav qhia txog qhov tshwj xeeb uas cov amino acids txuas ua ke los tsim cov protein.
  • Secondary Structure.
  • Tertiary Structure.
  • Quaternary Structure.

Koj txiav txim siab li cas cov qauv ntawm cov protein?

Muaj ntau txoj kev siv tam sim no txiav txim seb tus qauv ntawm cov protein , suav nrog X-ray crystallography, NMR spectroscopy, thiab electron microscopy. Txhua txoj kev muaj qhov zoo thiab qhov tsis zoo. Hauv txhua txoj hauv kev no, tus kws tshawb fawb siv ntau cov ntaub ntawv los tsim cov qauv atomic kawg.
