  2. Acetyl-CoA - Wikipedia

    en.wikipedia.org/wiki/Acetyl-CoA

    Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. [2] Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.

  3. Coenzyme A - Wikipedia

    en.wikipedia.org/wiki/Coenzyme_A

    In its acetyl form, coenzyme A is a highly versatile molecule, serving metabolic functions in both the anabolic and catabolic pathways. Acetyl-CoA is utilised in the post-translational regulation and allosteric regulation of pyruvate dehydrogenase and carboxylase to maintain and support the partition of pyruvate synthesis and degradation. [3]

  4. Beta oxidation - Wikipedia

    en.wikipedia.org/wiki/Beta_oxidation

    In biochemistry and metabolism, beta oxidation (also β-oxidation) is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA. Acetyl-CoA enters the citric acid cycle, generating NADH and FADH 2, which are electron carriers used in the ...

  5. Acetyl-CoA carboxylase - Wikipedia

    en.wikipedia.org/wiki/Acetyl-CoA_carboxylase

    The function of ACC is to regulate the metabolism of fatty acids. When the enzyme is active, the product, malonyl-CoA, is produced which is a building block for new fatty acids and can inhibit the transfer of the fatty acyl group from acyl-CoA to carnitine with carnitine acyltransferase , which inhibits the beta-oxidation of fatty acids in the ...

  6. Fatty acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_synthesis

    Acetyl-CoA is formed into malonyl-CoA by acetyl-CoA carboxylase, at which point malonyl-CoA is destined to feed into the fatty acid synthesis pathway. Acetyl-CoA carboxylase is the point of regulation in saturated straight-chain fatty acid synthesis, and is subject to both phosphorylation and allosteric regulation. Regulation by phosphorylation ...

  7. Citric acid cycle - Wikipedia

    en.wikipedia.org/wiki/Citric_acid_cycle

    Overview of the citric acid cycle. The citric acid cycle—also known as the Krebs cycle, Szent–Györgyi–Krebs cycle, or TCA cycle (tricarboxylic acid cycle) [1] [2] —is a series of biochemical reactions to release the energy stored in nutrients through the oxidation of acetyl-CoA derived from carbohydrates, fats, proteins, and alcohol.

  8. Acetate pathway - Wikipedia

    en.wikipedia.org/wiki/Acetate_pathway

    This pathway operates at the interface of central metabolism and specialized metabolite synthesis, playing a crucial role in the synthesis of both primary and secondary metabolites. [ 2 ] [ 3 ] [ 1 ] It begins with acetyl-CoA and involves the stepwise condensation of two-carbon units, typically derived from malonyl-CoA , to form increasingly ...

  9. Acetyl-CoA synthetase - Wikipedia

    en.wikipedia.org/wiki/Acetyl-CoA_synthetase

    Acetyl-CoA synthetase (ACS) or Acetate—CoA ligase is an enzyme (EC 6.2.1.1) involved in metabolism of acetate. It is in the ligase class of enzymes, meaning that it catalyzes the formation of a new chemical bond between two large molecules.
