New insights regarding the autooxidation
of polyunsaturated fatty acids.
It is very likely that the components of cranberry extract undergo oxidation reducing the oxidized molecules of phosphatidylcholine liposomes in an autooxidation
The assay is based on the ability of SOD to exhibit the autooxidation
of pyrogallol in presence of EDTA.
Gorkum, RV, Bouwman, E, Reedijk, J,"Fact Autooxidation
of Ethyl Linoleate Catalysed by Mn[(AcAc).
It is not possible to predict the degree of autooxidation
that might have occurred in the NPHSII samples over the storage period, and it is possible that total antioxidant status may decay at a variable rate, depending on the initial antioxidant content and availability of prooxidant factors.
The role of the superoxide anion in the autooxidation
of epinephrine and simple assay for superoxide dismutase.
Indeed, it has been suggested that hyperhomocysteinemia may promote the production of hydroxyl radicals, known to be lipid peroxidation initiators, via homocysteine autooxidation
and thiolactone formation (24, 26, 27).
The hydrogen abstraction or autooxidation
mechanism does not require any catalyst; however, cobalt ions do catalyze the degradation of hydroperoxides into alkyl, ether, and peroxide radicals, which accelerate the drying process considerably.
Before a diagnosis of gestational diabetes is made, usually during the second trimester, and before initiation of insulin therapy, oxidative stress and glucose autooxidation
may increase hydrogen peroxide generation and diminish catalase synthesis (5-12).
Before the discovery of tyrosine hydroxylase as the rate-limiting step in biosynthesis of catecholamines, researchers considered the possibility that endogenous catecholamines might arise from autooxidation
The determination of superoxide dismutase (SOD) activity was based on the inhibition of pyrogallol autooxidation
(Misra and Fridovich 1972).
Total SOD activity was assayed as the inhibition of the autooxidation
of pyrogallol in alkaline solution monitored at 420 nm (20), with 1 U of activity giving 50% inhibition at 10 min.
