Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide. AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine; it is an ester of phosphoric acid and the nucleoside adenosine. As a substituent it takes the form of the prefix adenylyl-.

AMP plays an important role in many cellular metabolic processes, being interconverted to ADP and/or ATP. AMP is used as a monomer in the synthesis of RNA.

AMP does not have the high energy pyrophosphate bond associated with ADP and ATP. AMP can be produced from ADP:

Or AMP may be produced by the hydrolysis of one high energy phosphate bond of ADP:

AMP can also be formed by hydrolysis of ATP into AMP and pyrophosphate:

When RNA is broken down by living systems, nucleoside monophosphates, including adenosine monophosphate, are formed.

AMP can be regenerated to ATP as follows:

AMP can be converted into IMP by the enzyme myoadenylate deaminase, freeing an ammonia group.

In a catabolic pathway, adenosine monophosphate can be converted to uric acid, which is excreted from the body.

AMP can also exist as a cyclic structure known as cyclic AMP (or cAMP). Within certain cells the enzyme adenylate cyclase makes cAMP from ATP, and typically this reaction is regulated by hormones such as adrenaline or glucagon. cAMP plays an important role in intracellular signaling.
