CKM (Creatine Kinase, Muscle): CKM is an enzyme specific to muscle tissue, where it plays a crucial role in energy metabolism by catalyzing the reversible transfer of phosphate between ATP and creatine to maintain a constant supply of ATP during muscle contraction. Elevated levels of CKM in the blood are indicative of muscle damage and are used as a biomarker for myocardial infarction, muscular dystrophy, and other conditions involving muscle injury....
