Flavin mononucleotide (FMN ) and riboflavin -5'-phosphate, is derived from vitamin riboflavin (vitamin B2). It acts as a coenzyme in various oxidoreductases including NADH dehydrogenase. During the catalytic cycle of the reaction, the compound passes from an oxidized state as FMN both semiquinone ( FMNH · ) and the reduced form ( FMNH2 ). FMN is a stronger oxidizing agent than NAD and is part of such reactions in which take place not only transfer of hydride ions ( ie two electrons), but single-electron transfers.

Use as dye

In food is riboflavin -5'-phosphate used as a yellow dye, and prepared for this synthesis of riboflavin. Use, it is used for example in the manufacture of creams, desserts, ice cream, sweets, cheese, mayonnaise, soups and pasta. No side effects are known for the human organism, it is considered harmless. In the EU there is a food additive with the E number 101 ( formerly E 107 ) allowed.
