Displaying 1 results of Phosphocreatine Stable Isotopes Phosphocreatine stable isotopes are used in research to study the biochemistry of energy metabolism. By replacing the naturally occurring isotopes with stable isotopes, researchers can track the movements of phosphocreatine and other metabolites in the body. This technique allows for a better understanding of how energy is stored and utilized in cells, as well as the effects of various interventions on these processes.
