- * * *N-(Aminoiminomethyl)-N-methylglycine; occurs in urine, sometimes as such, but generally as creatinine, and in muscle, generally as phosphocreatine. Elevated in urine in individuals with muscular dystrophy.- c. kinase (CK) an enzyme catalyzing the reversible transfer of phosphate from phosphocreatine to ADP, forming c. and ATP; of importance in muscle contraction. Certain isozymes are elevated in plasma following myocardial infarctions. SYN: c. phosphokinase.
* * *cre·atine 'krē-ə-.tēn, -ət-ən n a white crystalline nitrogenous substance C4H9N3O2 found esp. in vertebrate muscle either free or as phosphocreatine
* * *n.a product of protein metabolism found in muscle. Its phosphate, creatine phosphate (phosphocreatine, phosphagen), acts as a store of high-energy phosphate in muscle and serves to maintain adequate amounts of ATP (the source of energy for muscular contraction).
* * *cre·a·tine (kreґə-tin) [Gr. kreas flesh] an amino acid formed by methylation of guanidinoacetic acid, found in vertebrate tissues, particularly in muscle. Phosphorylated creatine (see phosphocreatine) is an important storage form of high energy phosphate, the energy source for muscle contraction.
