Since coenzyme A is, in chemical terms, a thiol, it can react with carboxylic acids to form thioesters, thus functioning as an acyl group carrier. It assists in transferring fatty acids from the cytoplasm to mitochondria.A molecule of coenzyme A carrying an acetyl group is also referred to as acetyl-CoA.oenzyme A is also the source of the phosphopantetheine group that is added as a prosthetic group to proteins such as acyl carrier protein and formyltetrahydrofolate dehydrogenase.
In this case the vitamins are called coenzyme vitamins. Some examples of coenzyme vitamins include Vitamin B1 in the form of thiamin diphosphate (or cocarboxylase) and Vitamin B6 in the form of pyridoxal 5â-phosphate. Coenzyme vitamins and direct precursors of coenzyme vitamins are found in foods in relatively small, but significant amounts.
