An isoenzyme (also known as Isozyme) is an enzyme that may appear in multiple forms, with slightly different chemical or other characteristics, and be produced in different organs, although each enzyme performs essentially the same function. The various forms are distinguishable in analysis of blood samples, which aids in the diagnosis of disease. All three of these isoenzymes make up the main enzyme CPK (creatine phosphokinase) (also called CK–creatine kinase). each isoenzyme can be isolated to different organs in the body and can help in diagnosing certain disorders.
