The denaturation of protein tend to the increased chances of autoxidation of Mb which results in significant color change due to low pH (Leygonie et al., 2012).
[6] Excess oxygen radicals may result from autoxidation of glucose.
Biodiesel fuel properties can degrade by one or more of the following mechanisms: (i) oxidation or autoxidation from contact with oxygen present in ambient air; (ii) thermal or thermal-oxidative decomposition from excess heat; (iii) hydrolysis from contact with water or moisture in tanks and fuel lines; or (iv) microbial contamination from migration of dust particles or water droplets containing bacteria or fungi into the fuel [12].
It involves generation of superoxide by pyrogallol autoxidation and inhibition of superoxide dependent reduction of tetrazolium dye MTT to its formazan.

Chronic hyperglycaemia results in the generation of free radicals due to increased production of mitochondrial ROS (Reactive Oxygen Species) by non-enzymatic glycation of proteins and glucose autoxidation. Elevated Free fatty acid can also result in oxidative stress due to increased mitochondrial uncoupling and oxidation leading to the increased production of ROS.

The reaction of organic substrates with atmospheric oxygen under mild conditions to form various oxygenated compounds such as hydroperoxides, peracids, epoxides, and ketones is called "autoxidation" [1].
In this context, the normal route of glycolysis gets saturated and excess glucose is shunted towards alternative ROS-forming pathways including glycosylation (Schiff reaction) [14], glucose autoxidation [15, 16], and glucosamine pathway [17], all of which lead to the accumulation of ROS and induction of oxidative stress.
