adenosine5monophosphate

Adenosine monophosphate, often abbreviated as AMP, is a nucleotide, a fundamental building block of nucleic acids such as RNA. It consists of a molecule of adenosine, which is composed of adenine and ribose, linked to a single phosphate group. AMP plays a crucial role in various biological processes.

In metabolism, AMP is a key intermediate. It is formed from adenosine diphosphate (ADP) by the removal of a phosphate group or from adenosine triphosphate (ATP) by the removal of two phosphate groups. The interconversion of ATP, ADP, and AMP is central to cellular energy transfer. ATP stores energy released from the breakdown of food, and when energy is needed, ATP is hydrolyzed to ADP, releasing energy. AMP can also be generated during periods of high energy demand.

Beyond its role in energy metabolism and nucleic acid synthesis, AMP is also involved in signal transduction. It acts as a precursor for cyclic adenosine monophosphate (cAMP), an important second messenger that mediates cellular responses to hormones and other extracellular signals. Furthermore, AMP can bind to specific receptors, influencing processes like blood flow regulation. The biological significance of AMP extends across all known forms of life.
