adenosine monophosphate(AMP) (ədĕn`əsēn mŏn'əfŏs`fāt), organic compound composed of an adenineadenine
, organic base of the purine family. Adenine combines with the sugar ribose to form adenosine, which in turn can be bonded with from one to three phosphoric acid units, yielding the three nucleotides adenosine monophosphate, adenosine diphosphate, and adenosine

(ATP) , organic compound composed of adenine, the sugar ribose, and three phosphate groups. ATP serves as the major energy source within the cell to drive a number of biological processes such as photosynthesis, muscle contraction, and the synthesis of

Cyclic AMP, a very close structural relative of AMP containing an additional ester linkage between the phosphate and ribose units, can act as a secondary messenger for several hormones. It also plays a role in the transcription of some genes (see nucleic acidnucleic acid,
