Molecular weight
Cyclic adenosine monophosphate (cAMP) is a second messenger used for intracellular signal induction. It is synthesized from adenosine triphosphate (ATP) by enzymes (g-proteins) that are attached to metabotropic receptors and become released when the receptor is activated. Cyclic AMP is involved in the regulation of glycogen, sugar, and lipid metabolism. This cAMP NHS ester is an excellent building block that can be used for developing cAMP probes and assays.
