Most fatty acids have an even number of carbon atoms and therefore are completely metabolized to acetyl-CoA. A fatty acid with an odd number of carbon atoms is metabolized to acetyl-CoA and one equivalent of propionyl-CoA. The following two reactions convert propionyl-CoA into succinyl-CoA, a citric acid cycle intermediate, so it can be further metabolized. Each of the enzyme- catalyzed reactions requires a coenzyme. Identify the coenzyme for each step. From what vitamins are the coenzymes derived?
