  2. Flavin adenine dinucleotide - Wikipedia

    en.wikipedia.org/wiki/Flavin_adenine_dinucleotide

    This makes the dinucleotide name misleading; however, the flavin mononucleotide group is still very close to a nucleotide in its structure and chemical properties. Reaction of FAD to form FADH 2 Approximate absorption spectrum for FAD. FAD can be reduced to FADH 2 through the addition of 2 H + and 2 e −.

  3. Flavin group - Wikipedia

    en.wikipedia.org/wiki/Flavin_group

    There are 18 key atoms in isoalloxazine that make up its characteristic three-ring structure. The R-group varies and differentiates various flavins. Riboflavin. Flavins (from Latin flavus, "yellow") refers generally to the class of organic compounds containing the tricyclic heterocycle isoalloxazine or its isomer alloxazine, and derivatives thereof.

  4. Coenzyme A - Wikipedia

    en.wikipedia.org/wiki/Coenzyme_A

    Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. All genomes sequenced to date encode enzymes that use coenzyme A as a substrate , and around 4% of cellular enzymes use it (or a thioester ) as a substrate.

  5. Acyl-CoA dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Acyl-CoA_dehydrogenase

    Structure of the medium-chain acyl-CoA dehydrogenase tetramer. FAD molecules are shown in yellow. The medium chain acyl-CoA dehydrogenase (MCAD) is the best known structure of all ACADs, and is the most commonly deficient enzyme within the class that leads to metabolic disorders in animals. [1]

  6. Beta oxidation - Wikipedia

    en.wikipedia.org/wiki/Beta_oxidation

    Acetyl-CoA enters the citric acid cycle, generating NADH and FADH 2, which are electron carriers used in the electron transport chain. It is named as such because the beta carbon of the fatty acid chain undergoes oxidation and is converted to a carbonyl group to start the cycle all over again.

  7. Dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Dehydrogenase

    The name "dehydrogenase" is based on the idea that it facilitates the removal (de-) of hydrogen (-hydrogen-) and is an enzyme (-ase). Dehydrogenase reactions come most commonly in two forms: the transfer of a hydride and release of a proton (often with water as a second reactant), and the transfer of two hydrogens.

  8. Acyl-CoA - Wikipedia

    en.wikipedia.org/wiki/Acyl-CoA

    This four step process repeats until acyl-CoA has removed all carbons from the chain, leaving only Acetyl-CoA. During one cycle of beta oxidation, Acyl-CoA creates one molecule of Acetyl-CoA, FADH2, and NADH. [7] Acetyl-CoA is then used in the citric acid cycle while FADH2 and NADH are sent to the electron transport chain. [8]

  9. Flavoprotein - Wikipedia

    en.wikipedia.org/wiki/Flavoprotein

    Its structure was determined and reported in 1935 and given the name riboflavin, derived from the ribityl side chain and yellow colour of the conjugated ring system. [ 6 ] The first evidence for the requirement of flavin as an enzyme cofactor came in 1935.
