, organic base of the purine family. Adenine combines with the sugar ribose to form adenosine, which in turn can be bonded with from one to three phosphoric acid units, yielding the three nucleotides adenosine monophosphate, adenosine diphosphate, and adenosine

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
