Creatine is a naturally occurring organic acid that is produced in body by the liver, kidneys, and
pancreas. Creatine can be absorbed from food, particularly from meat and fish. When food intake is low,
creatine is produced from the amino acids: glycine, arginine, and methionine in the liver, kidneys, and pancreas.
Michel Eugène Chevreul discovered creatine from skeletal muscles and named it creatine after the Greek word
Kreas meaning flesh.1
Creatine provides the energy necessary for vigorous muscle contraction and has been
shown to enhance performance in high-intensity exercise. Creatine supports high energy metabolism of ATP for
a short periods of time.2
Creatine exists in equilibrium with phosphocreatine, the reversible conversion of creatine into
phosphocreatine is catalyzed by the enzyme creatine kinase.1
Creatine phosphate is an ATP-synthesizer which
serves as a reservoir of high-potential phosphoryl groups that can be readily transferred to ATP. During
strenuous exercise, creatine phosphate regenerates ATP from ADP from creatine kinase.3
The reaction is
expressed below.
