Creatine kinase levels in patients with bipolar disorder. Creatine kinase is an important enzyme, particularly for cells with high and fluctuating energy requirements, such as neurons, and is a potential marker of brain injury. Serum levels of total creatine kinase varied in the sixhours period, showing a marked increase in the first two hours mean 6333 ul and slowly decreased by. Ck catalyses the conversion of creatine and uses adenosine triphosphate atp to create phosphocreatine pcr and adenosine diphosphate adp. Creatina quinasa international endurance group gse. An atypical electrophoretic creatine kinase ck band, which migrates between ckmm and ckmb and consists of either ckbb or ckmm complexed to another serum protein, often igg rarely iga or lipoprotein. The larger range in men is primarily because of the. Creatina quinasa ck, creatinquinasa, cpk oscar personal.
An elevated level of creatine kinase is seen in heart attacks, when the heart muscle is damaged, or in conditions that produce damage to the skeletal muscles or brain. This ck enzyme reaction is reversible and thus atp can be. Creatine kinase ck is also known as creatine phosphokinase cpk and is an enzyme that catalyzes the phosphorylation of creatine.
