A coenzyme primarily used by many enzymes of the oxidoreductase enzyme class. Flavin adenine dinucleotide (FAD) is employed either as a freely diffusible molecule or as a covalently bound prosthetic group within flavoproteins, which are proteins involved in oxidation-reduction (redox) reactions and that contain water-soluble yellow pigments called flavins. Biochemically, FAD is broadly important in biosynthesis and metabolism owing to its high electron-transfer potential.
