Creatine Kinase is an enzyme found in various tissues, including muscles and the brain. It plays a crucial role in energy production by converting creatine and adenosine triphosphate (ATP) into creatine phosphate and adenosine diphosphate (ADP). This process helps supply energy during high-intensity activities, such as exercise. Elevated levels of Creatine Kinase in the blood can indicate muscle damage or stress, making it a useful marker in medical diagnostics. Conditions like heart attacks, muscle disorders, and intense physical exertion can lead to increased enzyme levels, prompting further investigation by healthcare professionals.
