Oxidation of Lipids. IX. Decomposition of Methyl Linoleate and Methyl Linolenate Hydroperoxides in Solution

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...

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

Sageretia thea fruit extracts rich in methyl linoleate and methyl linolenate downregulate melanogenesis via the Akt/GSK3β signaling pathway

BACKGROUND/OBJECTIVES Sageretia thea is traditionally used as a medicinal herb to treat various diseases, including skin disorders, in China and Korea. This study evaluated the inhibitory effect of Sageretia thea fruit on melanogenesis and its underlying mechanisms in B16F10 mouse melanoma cells. The active chemical compounds in anti-melanogenesis were determined in Sageretia thea. MATERIALS/...

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 of Methyl Orange Solution with Potassium Peroxydisulfate

Oxidation of Methyl Orange (MO) solution in potassium peroxydisulfate (KPS) homogeneous reaction system without UV irradiation was investigated. The result shows that decolorization of MO increases as the dosage of K2S2O8 increases. The kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of MO ...
