The mechanism of the oxidative process, commonly referred to as autoxidation
, is a free-radical process that possesses initiation, propagation, and termination steps.
Pantothenate was stated to have no quenching effect on superoxide generated by pyrogallol autoxidation
until a supraphysiologic concentration of 3.
g] of polystyrene ([approximately equal to]100[degrees]C), a styrenated product is able to dry initially by solvent evaporation as opposed to the slow autoxidation
process required to "dry" oils.
Omeje EO, Okide GB, Esimone CO and U Ajali Kinetics of autoxidation
of an oil extract from Terminalia catappa.
The CVs show good precision both in plasma and serum except for 7[beta]-hydroxycholesterol, which can be formed during the preparation procedure by autoxidation
Because the findings of in vivo and in vitro research so strongly implicate the involvement of ROS in benzene-induced toxicity (Snyder and Hedli 1996), we designed a study to investigate the carcinogenic mechanism of benzene, focusing on BT, a benzene metabolite that generates ROS by autoxidation
(Kawanishi et al.
of human red cell lipids induced by hydrogen peroxide.
The theory was that pegs and plastics deteriorated because of a process called autoxidation
Oils containing unsaturated fatty acids have been shown to offer health benefits over their saturated counterparts, but are unfortunately significantly susceptible to autoxidation
Working at the university's Australian Research Council (ARC) Centre of Excellence for Free Radical Chemistry and Biotechnology, the scientists dismissed assumptions that plastics left in the sun, such as clothing pegs, inevitably become brittle through autoxidation
This method is based on the SOD-mediated increase in the rate of autoxidation
of 5,6,6,6 a,1 1 b tetrahydro - 3,9,10 - trihydroxybenzo (c) fluorine (TTF) in aqueous alkaline solution to yield a chromophore with maximum absorbance at 525 nm.
Under these conditions a variety of degradation reactions can occur, such as autoxidation
, thermal polymerization, thermal oxidation, isomerization, cyclization and hydrolysis (Predojevic, 2008), leading to less molecular weight compounds and therefore to a higher saponification value.
