acetyl coenzyme A
Quick Summary
Acetyl coenzyme A, also known as acetyl-CoA, is a crucial compound in metabolism. It is formed as an intermediate in metabolic pathways and plays an active role as a coenzyme in biological acetylations.12
Acetyl-CoA is central to the breakdown of fuel molecules like glucose, fatty acids, and some amino acids. Before these molecules can enter the tricarboxylic acid cycle, they are degraded into this two-carbon compound. Within the TCA cycle, acetyl-CoA is converted into carbon dioxide and energy.3
Furthermore, acetyl-CoA is a building block for synthesizing lipids, including fatty acids. The carbon atoms in fatty acids are derived from the acetyl-CoA produced during the breakdown of carbohydrates and other fatty acids.4

The oxidation of pyruvate to acetyl coenzyme A is inhibited by acetyl coenzyme A. Because acetyl coenzyme A also acts as a positive modulator of pyruvate carboxylation, this control reinforces the partition between pyruvate catabolism and its conversion to four-carbon intermediates for anaplerosis and gluconeogenesis.
