Acetyl-CoA is the prototypical member of the acyl-CoA thioesters. This is all done through a process called oxidative decarboxylation with the enzyme pyruvate dehydrogenase. The key difference between acetyl CoA and acyl CoA is that acetyl CoA (or acetyl Coenzyme A) helps in protein, carbohydrate, and lipid metabolism whereas acyl CoA (or acyl Coenzyme A) helps in the metabolism of fatty acids.. Acetyl CoA is very useful in delivering the acetyl group to the Krebs cycle for energy production. Beta oxidation takes place in four steps: dehydrogenation, hydration, oxidation and thyolisis. It is an essential cofactor or substrate for acetyltransferases and acyltransferases, as in the post-translational modification of proteins and in the synthesis of the neurotransmitter acetylcholine.
