Flavin Mononucleotide


(FMN; also riboflavin phosphate), a nonprotein component (coenzyme) of many flavoproteins, which are present in all living cells; a phosphorylated derivative of riboflavin. Molecular weight, 456.35.

FMN is freely soluble in water and insoluble in diethyl ether, chloroform, and methanol. In the organism it is synthesized from riboflavin and adenosine triphosphate (ATP) in the presence of the enzyme riboflavikinnase. As a constituent of flavoproteins, FMN takes part in the oxidation-reduction processes of organisms. It is the biochemical precursor of flavin adenine dinucleotide (FAD).

The acronym FMN is widely used in the biological literature.
