  Adenosine triphosphate - Wikipedia, the free encyclopedia
Adenosine 5'-triphosphate (ATP), discovered in 1929 by Karl Lohmann, is a multifunctional nucleotide primarily known in biochemistry as the "molecular currency" of intracellular energy transfer.
ATP consists of adenosine and three phosphate groups (triphosphate).
ATP is also synthesized through several so-called "replenishment" reactions catalyzed by the enzyme families of NDKs (nucleoside diphosphate kinases), which use other nucleoside triphosphates as a high-energy phosphate donor, and the ATP:guanido-phosphotransferase family, which uses creatine.

 Adenosine - Wikipedia, the free encyclopedia
Adenosine plays an important role in biochemical processes, such as energy transfer - as adenosine triphosphate (ATP) and adenosine diphosphate (ADP) - as well as in signal transduction as cyclic adenosine monophosphate, cAMP.
Because of the effects of adenosine on AV node-dependent SVTs, adenosine is considered a class V antiarrhythmic agent.

 Adenosine triphosphate
Adenosine triphosphate, (ATP) a molecule used by organisms to store energy.
Consists of three parts: sugar molecule (ribose), adenine base (a group consisting of linked rings of carbon and nitrogen atoms), and a phosphate chain which is key to the activity of ATP.
The molecule that results in this reaction is adenosine diphosphate (ADP) which can also lose its endmost phosphate group reducing to adenosine monophosphate (AMP).
