WebCofactor is a non-protein chemical compound that tightly and loosely binds with an enzyme or other protein molecules. Basically, cofactors are split into two groups: coenzymes and prosthetic groups (ions usually). WebA cofactor that is firmly bound to the apoenzyme and cannot be removed without denaturing the latter is termed a prosthetic group; most such groups contain an atom …

"Cofactors can be divided into two major groups: organic cofactors, such as flavin or heme; and inorganic cofactors, such as the metal ions Mg , Cu , Mn and iron–sulfur clusters. Organic cofactors are sometimes further divided into coenzymes and prosthetic groups. The term coenzyme refers specifically to enzymes and, as such, to the functional properties of a protein.
