Flavin mononucleotide (FMN) , also riboflavin 5'-phosphate, is derived from the vitamin riboflavin (vitamin B 2 ). It functions as a coenzyme in various oxidoreductases , including NADH dehydrogenase . During the catalytic reaction cycle, starting from the oxidized form as FMN, the compound passes through both the semiquinone - (FMNH · ) and the reduced form (FMNH 2 ). FMN is a stronger oxidizing agent than NAD and is part of such reactions in which not only transfers of hydride ions (i.e. two electrons), but also single electron transfers take place.
Use as a dye
Riboflavin-5'-phosphate is used as a yellow color in food and is produced synthetically from riboflavin. It is used, for example, in the production of cream dishes, desserts, ice cream , confectionery, cheese, mayonnaise , soups and pasta. No side effects are known for the human organism, it is considered harmless. In the EU it is approved as a food additive with the number E 101 (formerly also E 107).
