WebPhosphocreatine is the major phosphorylated compound present in muscles, eight times more than that of ATP. Enzyme activity is inhibited by excess ADP, urate, cysteine, and metal ions such as Mn2+, Ca 2+, Zn 2+ and Cu 2+. Mg 2+ is required for the activity of CK but excess of it inhibits the CK activity [51]. WebPhosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle, myocardium and the brain to recycle adenosine triphosphate, the energy currency of the cell.
