and photo-oxidation susceptibility of vegetable oils is one of the biggest problems of vegetable oil processing industry (Choe and Min, 2006).
Superoxide anion is involved in auto-oxidation
of pyrogallol at alkaline pH (8.
During the development of diabetes, hyperglycemia causes the increase in free radicals production especially reactive oxygen species (ROS) which attacks the tissues through the glucose auto-oxidation
and protein glycosylation mechanism .
MGO and glyoxal (GO) are reactive carbonyl compounds that are by-products of auto-oxidation
of glucose, lipid peroxidation and protein glycation, a process where protein and glucose interact, interfering with the function of protein in the body.
Two factors are primarily involved in auto-oxidation
of fats and oils, fatty acid composition and presence of antioxidant substances, the role of fatty acid profile is even more important than tocopherols .
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
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.
Two types of bad smells which could be removed by active juice packaging industry are amines, which are formed by decomposition of fish muscle proteins and aldehydes that comes from auto-oxidation
of fats and oils.
The uncontrolled hyperglycemia acts as a major player of auto-oxidation
of glucose, glycosylation of proteins and lipids leading to production of advanced glycation end products.
Al the second stage of aging after 26 days, namely auto-oxidation
period, the amount of crystalline phase increases abruptly and the amount of interphase and amorphous phase decrease simultaneously.
Adrenaline rapidly undergoes auto-oxidation
at pH 10, 7 producing adrenochrome, which is a pink colored product that can be measured at 480 nm with UV/VIS spectrophotometry.
