Acetyl Coenzyme A trisodium (Acetyl-CoA trisodium) is a central metabolic intermediate. Acetyl Coenzyme A trisodium is the actual molecule through which glycolytic pyruvate enters the tricarboxylic acid (TCA) cycle, is a key precursor of lipid synthesis, and is the sole donor of the acetyl groups for acetylation. Acetyl Coenzyme A trisodium acts as a potent allosteric activator of pyruvate carboxylase (PC).
