A cofactor is a non-protein chemical compound that is required for the protein's biological activity. These proteins are commonly enzymes, and cofactors can be considered helper molecules that assist in biochemical transformations.ach class of group-transfer reaction is carried out by a particular cofactor, which is the substrate for a set of enzymes that produce it, and a set of enzymes that consume it. An example of this are the dehydrogenases that use nicotinamide adenine dinucleotide (NAD +) as a cofactor.
If the cofactor is organic, then it is called a coenzyme. Coenzymes are relatively small molecules compared to the protein part of the â¦ Nonprotein components of certain enzymes are called cofactors.
