Description

Flavin mononucleotide, also known as riboflavin 5'-phosphate or flanin, 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. Flavin mononucleotide is an extremely weak basic (essentially neutral) compound (based on its pKa). Flavin mononucleotide exists in all living species, ranging from bacteria to humans.
