In different states, FAD has different colors. Like in a super oxidized state, it turns yellow-orange. In the fully oxidized state, it is yellow. In the half-reduced form, it is either red or blue-like pH, and if reduced fully, it becomes colorless. Both are derived from proteins and accept high-energy electrons and carry them to the electron transport chain.
Both are coenzymes. NAD is very important for carrying and delivering hydrogen and electrons in the biochemical process, whereas FAD uses electrons and hydrogen to make ATP.
Both are involved in the catabolic and anabolic processes through oxidation and reduction. Skip to content Coenzymes are very important for carrying out different reactions taking place in our body. NAD is Nicotinamide adenine dinucleotide. As you examine the reactions for metabolism, look for reactions that yield NADH. NADH will be important as it will deliver the hydrogens and electrons that it picks up to biochemical processes that can use the electrons and hydrogens to make ATP.
The hydrogen cation that is also captured in the reaction is released into the surrounding solution. Remember that this reaction is reversible. Flavin adenine dinucleotide in its oxidized state is called FAD.
After being reduced, it is called FADH 2. See figure 5 for a molecular illustration. The vitamin, riboflavin or B2 is used to derive this compound. Email required.

User assumes all risk of use, damage, or injury. However, in fermentation, two NADH molecules are produced during glycolysis and their regeneration occurs through substrate-level phosphorylation. FADH 2 is the reduced form of FAD flavin adenine dinucleotide made up of two joined nucleotides: adenine and flavin mononucleotide. Flavin-N 5 -oxide, quinone, semiquinone, and hydroquinone are the four, redox forms of FAD.
