Biotin yog a coenzyme Rau ntau cov carboxylase enzymes, uas koom nrog hauv kev zom cov carbohydrates, synthesis ntawm fatty acids, thiab gluconeogenesis. Biotin Nws kuj tseem yuav tsum tau siv rau catabolism thiab kev siv ntawm peb ceg-chain amino acids: leucine, isoleucine, thiab valine.
Tsis tas li, puas yog biotin yog cofactor?
Biotin , tseem hu ua vitamin B7 los yog vitamin H, yog ib qho tseem ceeb vitamin vim nws ua raws li ib tug cov cofactor rau tsib biotin -dependent carboxylase uas ua lub luag haujlwm tseem ceeb hauv cov metabolism hauv nruab nrab ntawm gluconeogenesis, fatty acid synthesis, thiab amino acid catabolism.
Ib yam li ntawd, cofactors coenzymes thiab prosthetic pawg yog dab tsi? Hlau ions feem ntau yog cofactors . Coenzymes yog ib hom kev pab lossis tus khub uas yog cov organic molecules xav tau rau kev ua haujlwm enzyme uas khi xoob rau ib qho enzyme. Lawv feem ntau, tab sis tsis tas li, muab los ntawm cov vitamins. Cov pab pawg neeg dag yog cov enzyme khub molecules uas khi nruj rau ib qho enzyme.
Kuj Paub, yog nad ib cofactor lossis coenzyme?
Cov pab pawg-hloov intermediates no yog cov organic uas xoob xoob cofactors , feem ntau hu ua coenzymes . Ib qho piv txwv ntawm qhov no yog cov dehydrogenases uas siv nicotinamide adenine dinucleotide ( NAD +) as a cov cofactor . Ntawm no, ntau pua hom sib cais ntawm cov enzymes tshem tawm cov electrons los ntawm lawv cov substrates thiab txo qis NAD + rau NADH.
Vim li cas biotin siv los ua coenzyme rau pyruvate carboxylase?
Pyruvate carboxylase siv covalently txuas biotin cofactor uas yog siv rau catalyze ATP- nyob ntawm carboxylation ntawm pyruvate ua rau oxaloacetate hauv ob kauj ruam. Biotin yog thawj zaug carboxylated ntawm BC active site los ntawm ATP thiab bicarbonate.
