Creatine Phosphate, Dipotassium Salt is a high-energy phosphate compound. Transfer of the phosphate group from creatine phosphate to ADP and from ATP to creatine form the basis of the creatine-creatine phosphate energy shuttle. It plays a role in energy metabolism, muscle contraction, cell growth, and cell signaling. It is also used in laboratory experiments to study the biochemical and physiological effects of creatine phosphate.
