Q

Acetyl coenzyme A (acetyl-CoA)

A

An important molecule in metabolism, used in many biochemical reactions. Its main use is to convey the carbon atoms within the acetyl group to the citric acid cycle to be oxidized for energy production. This compound forms the common entry point into the Kreb’s cycle for the oxidation of carbohydrate and fat.
