Creatine phosphate

Creatine Phosphate

Creatine phosphate (pronunciation: kree-uh-teen fahs-feyt), also known as phosphocreatine, is a naturally occurring organic compound that facilitates the recycling of adenosine triphosphate (ATP), the energy currency of the cell, primarily in muscle and brain tissue.

Etymology

The term "creatine" is derived from the Greek word "kreas," which means flesh. The term "phosphate" comes from the Greek word "phosphoros," which means bringer of light, referring to its role in the ATP-ADP cycle.

Function

Creatine phosphate is crucial for energy storage and release in cells. It acts as a buffer to maintain ATP levels, which is essential for normal functioning of the muscles. During periods of high-energy demand, creatine phosphate donates its phosphate group to adenosine diphosphate (ADP) to form ATP, which is then used as an energy source.
