A cosubstrate yog ib tus neeg koom nrog cov tshuaj tiv thaiv, uas tsim nyog rau kev tsim cov khoom xav tau, tab sis nws tsis yog lub ntsiab substrate rau cov tshuaj tiv thaiv tshwj xeeb. Cov tshuaj tiv thaiv no kuj tshwm sim tab sis nws tsis yog cov tshuaj tiv thaiv tseem ceeb catalysed los ntawm enzyme, txawm li cas los nws yog tsim nyog rau cov tshuaj tiv thaiv kom tiav.

Kuj nug, cov piv txwv ntawm cofactors yog dab tsi?

Cofactors tsis yog cov proteins tab sis theej pab cov proteins, xws li enzymes, txawm tias lawv tuaj yeem pab cov proteins uas tsis yog enzyme ib yam nkaus. Piv txwv ntawm cofactors suav nrog hlau ions xws li hlau thiab zinc.

Dab tsi yog coenzyme thiab nws txoj haujlwm yog dab tsi? Coenzymes yog me me molecules. Lawv tsis tuaj yeem los ntawm lawv tus kheej ua rau cov tshuaj tiv thaiv tab sis lawv tuaj yeem pab cov enzymes ua li ntawd. Hauv cov ntsiab lus technical, coenzymes yog cov organic nonprotein molecules uas khi nrog cov protein molecule (apoenzyme) los tsim cov active enzyme (holoenzyme).

Yog li ntawd, ob hom coenzymes yog dab tsi?

Cofactors tuaj yeem muab faib ua ob loj pab pawg : organic Cofactors, xws li flavin lossis heme, thiab inorganic cofactors, xws li cov hlau ions Mg2+, Cu+, Mn2+, los yog hlau-sulfur pawg. Organic cofactors qee zaum ntxiv muab faib ua coenzymes thiab prosthetic pab pawg.

Holoenzyme thiab Apoenzyme yog dab tsi?

Ib apoenzyme yog ib qho enzyme tsis ua haujlwm, ua kom cov enzyme tshwm sim thaum khi ntawm cov organic lossis inorganic cofactor. Holoenzyme - Ib apoenzyme ua ke nrog nws cov cofactor. A holoenzyme yog ua tiav thiab catalytically nquag. Feem ntau cov cofactors tsis yog covalently khi tab sis es tsis txhob nruj nruj.
