Creatine kinase (CK) is an enzyme found in muscle, brain, and other tissues. CK is released in increased quantities when muscle injury occurs.
Creatine kinase is an enzyme present in skeletal and cardiac muscle and in the brain. Very high levels in the blood can indicate the presence of disease or an abnormality.
An enzyme (a type of protein) used as a cardiac marker; all cells in the body have creatine kinase, but the type used as a cardiac marker is found mostly in the heart.
An enzyme present in skeletal muscle, cardiac muscle, and the brain. It catalyzes the high energy phosphate between creatine and phosphocreatine and between adenosine diphosphate (ADP) and adenosine triophosphate (ATP).
An isoenzyme (an enzyme that appears in multiple forms) found in high concentrations in heart and skeletal muscles, and, in smaller amounts, in brain tissue. Each form of CK is predominant in specific tissues. Determining blood levels of the isoenzyme will aid in detection of myocardial infarction and muscle diseases such as muscular dystrophy.
Creatine kinase (CK), also known as phosphocreatine kinase or creatine phosphokinase (CPK) is an enzyme expressed by various tissue types. Its function is the catalysis of the conversion of creatine to phosphocreatine, consuming adenosine triphosphate (ATP) and generating adenosine diphosphate (ADP) and the reverse reaction. In tissues that consume ATP rapidly, especially skeletal muscle, but also brain and smooth muscle, phosphocreatine serves as an energy reservoir for the rapid regeneration of ATP, the major source of energy in biochemical reactions.
