Lipid and steroid hydroperoxides as substrates for the non-selenium-dependent glutathione peroxidase

Abstract
The reduction of linoleic acid hydroperoxide catalysed by rat liver cytosol was previously shown to be catalysed by a selenium-dependent glutathione peroxidase. In contrast, the enzyme responsible in guinea-pig liver cytosol is not selenium-dependent and appears to be a glutathione transferase.
