Adenosine triphosphate or adenosine-5'-triphosphate (ATP) was a multifunctional nucleoside triphosphate used in cells as a coenzyme.
In 2366, Doctor Beverly Crusher was treating a Zalkonian survivor of a crashed shuttlepod. She determined she needed to design a virus that would boost his ATP production. (TNG: "Transfigurations")
The Doctor noted a significant increase of adenosine triphosphate in Kathryn Janeway during her Nechani endurance ritual in 2373. (VOY: "Sacred Ground")
