Adenosine diphosphate (ADP)

A coenzyme and an important intermediate in cellular metabolism as the partially dephosphorylated form of adenosine triphosphate. The compound is 5-adenylic acid with an additional phosphate group attached through a pyrophosphate bond. ADP is produced from adenosine triphosphate and reconverted to this compound in coupled reactions concerned with the energy metabolism of living systems. ADP is also produced from 5-adenylic acid by the transfer of a phosphate group from adenosine triphosphate in a reaction that is catalyzed by an enzyme, myokinase. See Metabolism
