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) and is therefore important in the transfer of chemical energy during anabolism. 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,
