Application

Acetyl-CoA is an essential cofactor and carrier of acyl groups in enzymatic acetyl transfer reactions. Acetyl CoA is formed either by the oxidative decarboxylation of pyruvate in mitochondria, by the oxidation of long-chain fatty acids, or by the oxidative degradation of certain amino acids. Acetyl-CoA is the starting compound for the citric acid cycle (Krebs cycle). Acetyl CoA is also a key precursor in lipid biosynthesis, and the source of all fatty acid carbons. Acetyl-CoA positively regulates the activity pyruvate carboxylase. Acetyl CoA is a precursor of the neurotransmitter acetylcholine. Histone acetylases (HAT) use Acetyl-CoA as the donor for the acetyl group use in the post-translational acetylation reactions of histone and non-histone proteins.

Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.
