flavin

 [fla´vin]
any of a group of water-soluble yellow pigments widely distributed in animals and plants, including riboflavin and yellow enzymes.
flavin adenine dinucleotide (FAD) a coenzyme that is a condensation product of riboflavin phosphate and adenylic acid; it forms the prosthetic group (non–amino acid component) of certain enzymes, including d-amino acid oxidase and xanthine oxidase, and is important in electron transport in mitochondria.
flavin mononucleotide (FMN) a derivative of riboflavin consisting of a three-ring system (isoalloxazine) attached to an alcohol (ribitol); it acts as a coenzyme for a number of oxidative enzymes, including l-amino acid oxidase and cytochrome C reductase.

fla·vin ad·e·nine di·nu·cle·o·tide (FAD),

a condensation product of riboflavin and adenosine 5'-diphosphate; the coenzyme of various aerobic dehydrogenases, for example, d-amino-acid oxidase and aldehyde dehydrogenase; strictly speaking, FAD is not a dinucleotide because it contains a sugar alcohol; the coenzyme is reversibly reduced to FADH2.
