ATP
ATP is “A TeePee”, but it also stands for Adenosine TriPhosphate, which is the life-giving energy in cells.
To remember the name, imagine a den of sin (adenosine) in a teepee being raided by the police. The police can’t get through the flap, so the leader of the operation says: “Try force mate!” (triphosphate).
