Metabolite Identification
Common NameInosine 2'-phosphate
DescriptionInosine 2'-phosphate is an inosine nucleotide containing a pyrophosphate group esterified to C2 of the sugar moiety. Inosine 2'-phosphate is a product of 2',3'-cyclic-nucleotide 3'-phosphodiesterase (EC 3.1.4.37). This enzyme (also called CNP) catalyzes the chemical reaction: nucleoside 2',3'-cyclic phosphate + H2O <-> nucleoside 2'-phosphate. 2',3'-cyclic nucleotide 3'-phosphodiesterase is a myelin-associated enzyme that makes up 4% of total CNS myelin protein, and is thought to undergo significant age-associated changes. The absence of CNP causes axonal swelling and neuronal degeneration.
