ATP

 (ā′tē′pē′)
n.
A nucleotide, C10H16N5O13P3, that is composed of adenosine and three phosphate groups and releases energy when hydrolyzed to ADP. It is present in all cells, where it is used to store and transport energy needed for biochemical reactions.

[a(denosine) t(ri)p(hosphate).]

ATP

n
(Biochemistry) adenosine triphosphate; a nucleotide found in the mitochondria of all plant and animal cells. It is the major source of energy for cellular reactions, this energy being released during its conversion to ADP. Formula: C10H16N5O13P3. Also called: ATPase

ATP

1. (Aeronautics) advanced turboprop
2. (Tennis) Association of Tennis Professionals
3. (Railways) automatic train protection: a safety system which automatically prevents a train from passing through a stop signal

ATP

adenosine triphosphate: a nucleotide that is the primary source of energy in all living cells because of its function in donating a phosphate group during biochemical activities; composed of adenosine, ribose, and three phosphate groups and formed by enzymatic reaction from adenosine diphosphate and an orthophosphate. Compare ADP.

ATP

(ā′tē′pē′)
Short for adenosine triphosphate. An organic compound, C10H16N5O13P3, that is composed of adenosine and three phosphate groups. It serves as a source of energy for many metabolic processes. ATP releases energy when it is broken down into ADP by hydrolysis during cell metabolism.
