Creatinine phosphate is a high-energy substance, releasing approximately 1.5 times the energy of ATP. ATP is the body's direct energy source, and the energy released from ATP can be converted into ADP. Then, through the action of creatine kinase, creatine phosphate quickly provides ADP with a phosphate group, generating ATP again and restoring normal high ATP levels. Creatine phosphate, after losing its phosphate group, can be phosphorylated by ATP again, regenerating creatine phosphate. Creatinine phosphate and its salts can be used to synthesize creatine phosphate and its salts.
