Description
Glutathione peroxidase is an enzyme which reduced lipid hydroperoxides into their corresponding alcohols. It also reduces free hydrogen peroxide in to water. In vivo it is responsible for protecting hemoglobin from oxidative breakdown.

Product Overview
At the reported pH optimum of 8.8, we have found the activity to be approx. 10 times that at pH 7.0. However, to remain consistent with literature and avoid complications arising from non-enzymatic oxidation of GSH, our unit is defined at pH 7.0.
Form
Lyophilized powder containing 25% sucrose, 3% dithiothreitol, and sodium phosphate buffer salts
Enzyme Commission Number
EC 1.11.1.9
Activity
> 30 units/mg protein
Unit Definition
One unit will catalyze the oxidation by H2O2 of 1.0 μmole of reduced glutathione to oxidized glutathione per min at pH 7.0 at 25°C.
