Fatty acid composition had a major effect on the rise of peroxide value in the oxidation chamber, oils rich in monounsaturated fatty acids are usually more stable to auto-oxidation, and therefore, CO yielded the lowest peroxide value as compared to SBO and SFO.
The antioxidant capacity of b-carotene combined with a-tocopherol was inferior to a-tocopherol alone because its auto-oxidation weakened the effect of alpha-tocopherol.
Because of the pyrite auto-oxidation, fresh coal mine spoil is associated with high temperature, acid production and devoid of available organic nutrients, and expected to be inhabited by the extremophiles such as thermo-tolerant heterotrophs (Norris et al.

Above 150[degrees]C, the dissolved oxygen forms free radicals, initiating auto-oxidation and leading to coke deposits.
Although LTX-diol identified as the peak II component isolated from ground corncob in this study is an auto-oxidation product of linoleic acid in animals, a cytosolic epoxide hydrolase can metabolize the epoxy fatty esters to their vicinol diols (Halankar et al.
