Hauv biochemistry, flavin adenine dinucleotide ( FAD ) yog ib qho redox-active coenzyme txuam nrog ntau yam proteins, uas yog koom nrog ntau yam tseem ceeb enzymatic tshwm sim hauv cov metabolism. Ib qho flavoprotein yog ib qho protein uas muaj cov pab pawg flavin, qhov no yuav yog nyob rau hauv daim ntawv ntawm FAD los yog flavin mononucleotide ( FMN ).

Tib neeg kuj nug tias, FMN lub luag haujlwm yog dab tsi?

FMN yog ib qho flavin mononucleotide uas yog riboflavin (vitamin B2) uas thawj pawg hydroxy tau hloov mus rau nws cov dihydrogen phosphate ester. Nws muaj ib lub luag hauj lwm raws li ib tug coenzyme, cov kab mob metabolite, tib neeg metabolite, nas metabolite thiab cofactor.

Kuj Paub, FMN puas yog tus xa khoom hluav taws xob? Lo lus tseem ceeb - FMN (KW-0288) FMN yog ib electron cab kuj molecule uas ua haujlwm raws li hydrogen txais.

Ua li no, FMN sawv cev rau dab tsi hauv biochemistry?

Flavin mononucleotide ( FMN ), los yog riboflavin-5'-phosphate, yog biomolecule tsim los ntawm riboflavin (vitamin B.2) los ntawm cov enzyme riboflavin kinase thiab ua haujlwm raws li cov pab pawg pob txha ntawm ntau yam oxidoreductases, suav nrog NADH dehydrogenase, nrog rau cofactor hauv cov xim xiav-lub teeb duab receptors.

Vim li cas fad yog cofactor?

FAD los yog flavin adenine dinucleotide yog ib hom coenzyme heev (a cofactor ua los ntawm cov organic molecules) nyob rau hauv cov proteins. Zoo ib yam li NAD thiab NADP nyob rau hauv uas nws nqa electrons, FAD koom nrog ntau yam tshuaj lom neeg tseem ceeb uas flavoproteins nqa tawm.
