| Common Name | FADH |
|---|
| Description | FADH 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. |
