Line 1:

'''Flavin''' is a tricyclic heteronuclear organic ring whose biochemical source is the vitamin [[riboflavin]]. The flavin moiety is often conjugated with an [[adenosine diphosphate]] to form '''flavin adenine dinucleotide''' (e.g. '''FAD'''), and in other circumstances, is found as '''flavin mononucleotide''' (or '''FMN'''), a phosphorylated form of [[riboflavin]]. The flavin group is capable of undergoing oxidation-reduction reactions, and can accept either one electron in a two step process or can accept two electrons at once. ItIn the form of FADH₂, it is one of the cofactors that can transfer electrons to the [[Electron_transfer_chain|electron transfer chain]]. FMN is a prosthetic group found in [[NADH dehydrogenase]] and FAD is a cofactor in the enzymes D-amino acid oxidase and glucose oxidase.
