Acetyl coenzyme A-d3 (Acetyl-CoA-d3) is the deuterium labeled Acetyl coenzyme A (HY-114293). Acetyl-coenzyme A (Acetyl-CoA) is a membrane-impermeant central metabolic intermediate, participates in the TCA cycle and oxidative phosphorylation metabolism. Acetyl-coenzyme A, regulates various cellular mechanisms by providing (sole donor) acetyl groups to target amino acid residues for post-translational acetylation reactions of proteins. Acetyl Coenzyme A is also a key precursor of lipid synthesis[1][2][3][4].
