Phosphagen
Phosphagen
Phosphagen (pronounced: /ˈfɒsfədʒɛn/) is a type of high-energy phosphate compound found in muscle tissue. It is used by the body to rapidly generate ATP, the main energy currency of cells, during short, intense bursts of activity.
Etymology
The term "phosphagen" is derived from the Greek words "phosphoros" meaning "light-bringer" and "genes" meaning "born of, produced by". This is in reference to the compound's role in energy production.
Function
Phosphagens function as part of the Phosphagen system, a biochemical pathway that rapidly generates ATP from ADP in the presence of a phosphagen. The most well-known phosphagen is Creatine phosphate, which is synthesized in the liver, kidneys, and pancreas and transported to muscle cells.
