Most fatty acids have an even number of carbons and, therefore, are completely metabolized to acetyl-CoA. A fatty acid with an odd number of carbons 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 reactions requires a coenzyme. Identify the coenzyme for each step. From what vitamins are the coenzymes derived?

- Acyl-CoA synthase is the enzyme that activates a fatty acid by converting it to a fatty acyl-CoA in a series of two reactions. In the first reaction, the fatty acid reacts with ATP and one of the products formed is ADP. The other product reacts in a second reaction with CoASH to form the fatty acyl-CoA. Propose a mechanism for each of the reactions.arrow_forwardFatty acids and triglycerides are an important source of nutrition and a dense form of stored energy.
