propionylCoAta
Propionyl-CoA (also written propionyl coenzyme A) is a metabolically significant molecule derived from the breakdown of certain amino acids and fatty acids. It is a thioester formed between propionic acid and coenzyme A. The primary metabolic pathways that generate propionyl-CoA include the catabolism of odd-chain fatty acids, the breakdown of the amino acids valine, isoleucine, threonine, and methionine, and the metabolism of cholesterol.
Once formed, propionyl-CoA enters a crucial metabolic pathway known as the propionyl-CoA carboxylase reaction. In this
Succinyl-CoA is an intermediate in the citric acid cycle (also known as the Krebs cycle or TCA
