Natural Product Identification
Common NameFADH
DescriptionFADH is the reduced form of flavin adenine dinucleotide (FAD). FAD is synthesized from riboflavin and two molecules of ATP. Riboflavin is phosphorylated by ATP to give riboflavin 5-phosphate (FMN). FAD is then formed from FMN by the transfer of an AMP moiety from a second molecule of ATP. FADH is generated in each round of fatty acid oxidation, and the fatty acyl chain is shortened by two carbon atoms as a result of these reactions; because oxidation is on the beta carbon, this series of reactions is called the beta-oxidation pathway. In the citric acid cycle, FADH is involved in the harvesting of high-energy electrons from carbon fuels; the citric acid cycle itself neither generates a large amount of ATP nor includes oxygen as a reactant. Instead, the citric acid cycle removes electrons from acetyl CoA and uses these electrons to form FADH.
