2), we can observe different band assignments that belong to chemical groups or bonds according to autooxidation mechanism.
These results were in accordance with previous findings investigating the toxicity by using the Photobacterium test indicating comparably high toxicity of high molecular autooxidation products of phenolic compounds.
Since 7[alpha]-hydroxycholesterol can be formed via autooxidation of cholesterol, it is plausible that the elevated plasma levels of 7[alpha]-hydroxycholesterol in the HFC dietary treatment group are a result of increased cholesterol autooxidation due to the observed hypercholesterolemia in these mice.
Among the mechanisms, these molecules can increase their intracellular concentrations through the autooxidation of glucose resulting in glyoxal [4] that can undergo a final fragmentation producing the methylglyoxal [5].
Then, the products of this stage react with additional lipids to form other reactive chemical species--often termed "autooxidation." In the final termination (secondary) phase, relatively unreactive compounds are formed, including hydrocarbons, aldehydes, and ketones.
It involves the generation of superoxide by pyrogallol autooxidation and inhibition of superoxide dependent reduction of the tetrazolium dye MTT [3-(4-5 dimethylthiazol 2-yl) 2,5-diphenyltetrazolium bromide] to its formazan, which is measured at 570 nm.
Thus, the formation of ROS by the autooxidation of 6-OHDA is considered as the main molecular mechanism underlying the neurotoxicity of 6-OHDA [29-31].
Two HoCys molecules can undergo autooxidation and form a dimer (homocysteine: oxidized disulfide) by liberating two hydrogenions and two electrons.
The answer is that in the presence of oxygen, vitamin C undergoes autooxidation at physiological pH, a reaction not significantly slowed by the EDTA-facilitated removal of transition metal cations.
The porphyrins can undergo photo-oxidation and autooxidation generating free radicals.
Cure was by autooxidation. Cis-1, 4 liquid polybutadienes also can be maleinized to yield electrodepositable polymers.
