Creatine phosphoric acid, also known as creatine phosphate, is an important molecule present in all muscle cells. It provides a quick source of energy for muscular contractions and is essential for high-intensity exercises such as weightlifting and sprinting. There are several synonyms for creatine phosphoric acid including creatine phosphate, phosphocreatine, and N-phosphocreatine. All these terms refer to the same molecule that plays a significant role in muscle function. While creatine phosphoric acid is primarily associated with athletic performance, it also has potential therapeutic applications in the treatment of certain neurological and muscular disorders.
