Vitamins (Act as Cofactors or Coenzymes)
Vitamins are medium sized biomolecules which contain carbon and are, therefore, organic molecules.
Vitamins are organic chemicals that a given living organism requires in trace quantities for good health, but which the organism cannot synthesize, and therefore must obtain from its diet.
