Metabolite IDPAMDB000020
Name: Cyclic AMP
Description:Cyclic AMP is an adenine nucleotide containing one phosphate group which is esterified to both the 3'- and 5'-positions of the sugar moiety. It is a second messenger and a key intracellular regulator. cAMP is synthesized from ATP by adenylate cyclase. Adenylate cyclase is located at the cell membranes. cAMP decomposition into AMP is catalyzed by the enzyme phosphodiesterase.
