Oxidation of Lipids. V. Oxidation of Methyl Linoleate in Aqueous Dispersion

Mutagenicity tests of lipid oxidation products in Salmonella typhimurium: monohydroperoxides and secondary oxidation products of methyl linoleate and methyl linolenate.

Nine hydroperoxy and hydroperoxy-epidioxy oxidation products derived from either autoxidation (AO) or photosensitized oxidation (PO) of methyl linoleate (MLo) or methyl linolenate (MLn) were tested for mutagenic activity by the Salmonella typhimurium his+ reversion assay using strains TA100, TA98, TA102, TA97 and TA1537. All nine oxidation products, monohydroperoxides from AO-MLn (I) or from PO...

Inhibition of oxidation of methyl linoleate in solution by vitamin E and vitamin C.

The oxidation of methyl linoleate in solution initiated with azo compounds has been studied in the absence and presence of vitamin E and vitamin C. Both vitamin E and vitamin C acted as a chain-breaking antioxidant and they suppressed the oxidation and produced an induction period. The inhibition rate constant for the scavenging of peroxy radical was calculated at 37 degrees C as kinh = 5.1 X 1...

Oxidation Kinetics of Methyl Linoleate and α-Linolenate in Bulk and Oil-in-water Emulsion Systems

The Effect of Bixin and Carotene on the Oxidation of Methyl Linoleate

While the coupled oxidation of carotene and oils has been studied in some detail (l-7), the r6le of other carotenoids in oxidizing oils is imperfectly understood. Indications that bixin is oxidatively destroyed in a manner similar to carotene were given in the study of lipoxidase by Sumner and Smith (8). Solutions of bixin were also observed to be vastly more stable than similar solutions of ca...
