a·den·o·sine 3',5'-cy·clic mo·no·phos·phate (cAMP),

(ă-den'ō-sēn sī'klik mo'nō-fos'fāt),
An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; the first compound referred to as a "second messenger." It is a metabolic regulator. A related compound (2',3') is also known.

a·den·o·sine 3',5'-cy·clic mo·no·phos·phate

(cAMP) (ă-den'ō-sēn sik'lik mon'ō-fos'fāt)
An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from adenosine triphosphate by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known.
Synonym(s): cyclic AMP.

adenosine 3′,5′-cyclic monophosphate

Abbreviation: AMP
A cyclic form of adenosine. Its synthesis from adenosine triphosphate (ATP) is stimulated by an enzyme, adenylate cyclase (also called cyclic AMP synthetase). Adenosine 3′,5′-cyclic monophosphate is important in a wide variety of metabolic responses to cell stimuli.
