ATP (Adenosine triphosphate)
0901202-5
[DEFINITION]
Abbreviation of adenosine triphosphate (C10H16N5O13P3). Adenosine
is aćribonucleotide composed of adenine, which is a base, and combined with ribose, which is a
pentose. Adenosine triphosphate is composed of adenosine and, in addition, combined with a series
of three molecules of phosphoric acid.
[DESCRIPTION]
When ATP is hydrolyzed and releases one molecule of phosphoric acid
to turn into adenosine diphosphate (ADP) or two molecules to turn into adenosine monophosphate (AMP),
it also releases thermal energy and free energy. In the reverse reaction, ATP can store energy.
ATP is a crucial substance for energy storage and supply, transportation and so on, in living
organisms. For example, ATP plays a part in various in vivo reactions and processes where much
energy is acquired or used, such as metabolism and synthesis of various substances, motion of
muscles, bioluminescence, and so on.
