In biodiesel, the fatty acids are esterified and hence the auto-oxidation
is decreased, which all results in a reduction of PV.
It is widely accepted that genetic mutations, mitochondrial dysfunction, dopamine auto-oxidation
, neuroinflammation, and iron accumulation contribute significantly to the pathogenesis of PD.
SFO, SBO and CO yielded the varying extents of oxidation product, also their extent was considerably lower than their controls (P<0.05) which revealed that the addition of SLE had a pronounced effect on the inhibition of auto-oxidation
in these oils during long term storage at ambient temperature.
of unsaturated fatty acids involves the formation of semistable peroxides, which then undergo a series of reactions to form MDA.
The glucose auto-oxidation
and protein glycosylation have the potential to cause a catastrophic damage as a result of the free radical attack, and complex antioxidant defence mechanisms have evolved to protect the body cells and tissues .
The contribution of fatty acids in process of auto-oxidation
of is 24%, whereas the contribution of tocopherols in the inhibition of lipid peroxidation phenomenon was lesser than those contributed by the fatty acid profile .
of fats and oil in processed foods may be prevented by use of oxidation inhibitors or antioxidants.
Dermatological and cosmetic formulations contain fragrance, fats and oils, which are all subject to auto-oxidation
by exposure to air, causing off odor and chemical degradation.
Polyunsaturated fatty acids react with molecular oxygen to undergo destructive free radical mediated auto-oxidation
. During this process numerous peroxides and aldehyde compounds are formed.
of fatty compounds is accentuated by factors such as presence of air, heat, traces of metal, peroxides as well as nature (structure) of the fatty acid compound.
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., 1986; Kuenen et al., 1992; Shennan, 1996; Rawlings et al., 1999 and Akbar et al., 2005), acid tolerant bacteria (Wood and Kelly, 1986; Norris, 1990; Kristjansson and Stetter, 1992; Shennan, 1996; Wulf-Durand et al., 1997; Rawlings et al., 1999; Kristjansson et al., 2000; Akbar et al., 2005).
Aldehydes, mostly hexanal, are the most significant class of odorous compounds formed due to the auto-oxidation
and photo-oxidation of unsaturated lipid compounds (Fig.
