Chemical Information
FooDB NameFMNH
DescriptionFMNH2, also known as FMNH or reduced FMN, belongs to the class of organic compounds known as flavin nucleotides. These are nucleotides containing a flavin moiety. Flavin is a compound that contains the tricyclic isoalloxazine ring system, which bears 2 oxo groups at the 2- and 4-positions. FMNH2 is an extremely weak basic (essentially neutral) compound (based on its pKa). FMNH2 exists in all living species, ranging from bacteria to humans. Within humans, FMNH2 participates in a number of enzymatic reactions. In particular, 24,25-dihydrolanosterol and FMNH2 can be converted into formic acid, flavin mononucleotide, and 4,4-dimethyl-14α-hydroxymethyl-5α-cholesta-8-en-3β-ol through its interaction with the enzyme lanosterol 14-alpha demethylase. In addition, 4,4-dimethyl-14α-hydroxymethyl-5α-cholesta-8-en-3β-ol and FMNH2 can be converted into 4,4-dimethyl-14α-formyl-5α-cholest-8-en-3β-ol, flavin mononucleotide, and formic acid through its interaction with the enzyme lanosterol 14-alpha demethylase. The reduced 1,5-dihydro form of flavin mononucleotide. In humans, FMNH2 is involved in kandutsch-russell pathway (cholesterol biosynthesis).
