General description

Hydrogen peroxide-18O2, isotopically labeled analogue of hydrogen peroxide.

Application

18O-labeled H2O2 is used to determine absolute rate and pathway of peroxide formation and decay processes in surface waters of a coastal marine site and also use to measure absolute rates of dark H2O2 production in freshwater systems. It is used to study the acetylcoenzyme A (Ac-CoA) metabolism and potential therapeutic approach for cognitive disabilities on D(16) mouse model of down syndrome.
