Reduction of various lipid hydroperoxides by rat liver homogenate.
Rates of disappearance of hydroperoxy groups of various lipid peroxides added to rat liver homogenate differed from each other. The hydroperoxy group of linoleic acid disappeared rapidly, while those of L-3-phosphatidyl choline dilinoleoyl and trilinolenin disappeared slowly. The hydroperoxy groups of cholesterol linoleate were stable in the homogenate. Most of the conjugated dienes of these lipid peroxides remained. The hydroperoxy groups of the unsaturated fatty acids of the phosphatidyl choline were found to be changed to hydroxy groups as analyzed by high-performance liquid chromatography.
