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.

WebCofactors or coenzymes are prosthetic groups that connect to enzymes and aid in their action. A holoenzyme is a protein that has a prosthetic group, while a holoprotein is any protein that has a prosthetic group. Examples: Non-protein components known as prosthetic groups bind to proteins and help them in a variety of ways.
