Phosphocreatine is a substance that, in its chemical partnership with adenosine triphosphate (ATP), is fundamental to the ability of the body to produce muscular energy.hen phosphocreatine in the muscle breaks down, it is not reprocessed into a working form. Phosphocreatine metabolizes into a substance known as creatinine, which is excreted through the kidneys and passed as urine.
The amount of phosphocreatine available to restore ATP through periods of intense muscle exercise are small. It is for this reason that muscle fatigue will be noticeable to the athlete through this process, even when the activity is of short duration.hosphocreatine, which is also known as creatine phosphate is a compound constructed of carbon, hydrogen, nitrogen, oxygen, and phosphorus, in the molecular structure C 4 H 10 N 3 O 5 P. Phosphocreatine is formed naturally within the body, with over 95% of the compound stored within the muscle cells.
