±â´É
- Flavoproteins of electron transport chain, including FMN in Complex I and FAD in Complex II
- production of pyridoxic acid from pyridoxal (vitamin B6) by pyridoxine 5'-phosphate oxidase
- vitamin B6 (pyridoxal phosphate) is FMN dependent
- Oxidation of pyruvate, ¥á-ketoglutarate, and branched-chain amino acids
- Fatty acyl CoA dehydrogenase requires FAD in fatty acid oxidation
- retinol (vitamin A) to retinoic acid via cytosolic retinal dehydrogenase
- folate (5-methyltetrahydrofolate) from 5,10-methylenetetrahydrofolate by Methylenetetrahydrofolate
- FAD is required to convert tryptophan to niacin (vitamin B3)
- glutathione (GSSG) -(GSH) by Glutathione reductase is FAD dependent

The nucleotide part of the molecule does not enter into any chemistry, but is important for recognition and binding to enzymes that will use FMN or FAD as a cofactor.

The isoalloxazine ring is the core structure of the different flavin molecules. It is yellow in color and the word "flavin" is derived from the latin word for yellow, flavus.
Flavin coenzymes can exists in three different redox states, and each state has a different color (the reduced form is colorless)
Flavin molecules can participate in both one- and two- electron transfer reactions
