  2. Flavin adenine dinucleotide - Wikipedia

    en.wikipedia.org/wiki/Flavin_adenine_dinucleotide

    FADH 2 is an energy-carrying molecule, because, once oxidized it regains aromaticity and releases the energy represented by this stabilization. [citation needed] The spectroscopic properties of FAD and its variants allows for reaction monitoring by use of UV-VIS absorption and fluorescence spectroscopies.

  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.

    The reaction is easily reversible, when NADH reduces another molecule and is re-oxidized to NAD +. This means the coenzyme can continuously cycle between the NAD + and NADH forms without being consumed. [5] In appearance, all forms of this coenzyme are white amorphous powders that are hygroscopic and highly water-soluble. [8]

    The net gain from one cycle is 3 NADH and 1 FADH 2 as hydrogen (proton plus electron) carrying compounds and 1 high-energy GTP, which may subsequently be used to produce ATP. Thus, the total yield from 1 glucose molecule (2 pyruvate molecules) is 6 NADH, 2 FADH 2, and 2 ATP. [12] [13] [8]: 90–91

    In practice, it is closer to 14 ATP for a full oxidation cycle as 2.5 ATP per NADH molecule is produced, 1.5 ATP per each FADH 2 molecule is produced and Acetyl-CoA produces 10 ATP per rotation of the citric acid cycle [13] (according to the P/O ratio). This breakdown is as follows:

  7. 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]

  8. Dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Dehydrogenase

    Oxidoreductases, enzymes that catalyze oxidation-reduction reactions, constitute Class EC 1 of the IUBMB classification of enzyme-catalyzed reactions. [2] Any of these may be called dehydrogenases, especially those in which NAD + is the electron acceptor (oxidant), but reductase is also used when the physiological emphasis on reduction of the substrate, and oxidase is used only when O 2 is the ...

    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]
