Metabolite Identification
Common NameAdenosine 2',3'-cyclic phosphate
DescriptionAdenosine 2',3'-cyclic phosphate, also known as 2',3'-cyclic AMP or adenosine cyclic 2',3'-monophosphate, belongs to the class of organic compounds known as 2',3'-cyclic purine nucleotides. These are purine nucleotides in which the oxygen atoms linked to the C2 and C3 carbon atoms of the ribose moiety are both bonded the same phosphorus atom of the phosphate group. Adenosine 2',3'-cyclic phosphate is a strong basic compound (based on its pKa).
