One of the main molecules found in most cells
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
the primary energy-carrying molecule within cells, acting as the main energy currency for most cellular processes
When consumed in a metabolic process, adenosine triphosphate converts either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP).
