Adenosine Triphosphate (ATP) is used to increase physical energy.
Adenosine is a purine nucleotide that is present in all human cells. It contains a purine base, adenine, plus a ribose sugar, and can have 1 to 3 phosphate groups. Adenosine is involved in many physiological processes including cellular metabolism, nucleic acid synthesis, neurotransmission, muscle contraction, cardiac function, platelet function, vasodilation and liver glycogen metabolism. Adenosine Triphosphate (ATP) is broken down to adenosine diphosphate (ADP), then to adenosine monophosphate (AMP) and then to adenosine.
