Retrieved from https://www.thoughtco.com/definition-of-coenzyme-and-examples-604932. WHAT ARE THE ROLES OF VITAMIN Q? While enzymes are proteins, coenzymes are small, nonprotein molecules. Coenzyme Q10 is a substance similar to a vitamin that is found in every cell of the body. This process often requires several metabolic steps, which in turn are dependent on numerous other nutrients which are partly removed from the body. A coenzyme is technically a type of cofactor. They bind loosely to the enzyme and provide the transferring site for them. An Explanation of the Process of Hydrolysis, Chemistry Vocabulary Terms You Should Know, The Most Important Molecules in Your Body. Vitamins work together in impressive ways as coenzymes or precursors to coenzymes. Vitamins are organic compounds that are essential in very small (trace) amounts for the maintenance of normal metabolism. Coenzymes and vitamins. You can think of a coenzyme or cosubstrate as a helper molecule that aids an enzyme in catalyzing a chemical reaction. The acyl carrier protein is part of the enzymatic complex used for fatty acid synthesis and it is, therefore, essential for lipogenesis. It has been suggested that the AMP part of the molecule can be considered to be a kind of … Many (not all) are vitamins or are derived from vitamins. This coenzyme has several different functions.
