Oxidation with ozone, under physiological conditions, follows the rate order uric acid ascorbic acid > glutathione. The amounts of ozone absorbed and antioxidant consumed have been simulated with a mathematical model and reaction rate constants of the oxidations have been evaluated.194 Various facets of transition metal-catalysed oxidation of benzylic compounds with ozone have been reported. The correlation of the effect of substituents with Hammett constants and steric factors has been discussed. The reaction seemed to proceed via a radical mechanism.195... 

Previous studies have shown that rats maintained on a vitamin E-deficient diet had higher mortality rate than those of the -supplemented group when subjected to an acute dose of smoking exposure (42). Relatively greater increases in the levels of ascorbic acid, glutathione and related enzymes, glutathione-S-... 

Photoreductions of free base porphyrins and metal complexes with a variety of reducing agents, including ascorbic acid, glutathione, ethylene-diaminetetraacetic acid (EDTA), and acetoacetate, have been studied mainly from a mechanistic point of view (75MI6). Unstable hydroporphyrins of phlorin type VI are formed, which subsequently isomerize to chlorins, bacteriochlorins, or isobacteriochlorins.

Amperometric detection of hydrogen peroxide suffers also from interferences from other oxidizable substances present in biological fluids (ascorbic acid, glutathione, cysteine, uric acid, bilirubin). These problems are eliminated by hydrogen peroxide-permselective membranes [197, 198], by simultaneous use of a non-enzymatic membrane electrode...

Antioxidants can remove the harmful effects of these free radicals. Saliva is a natural defense against bacteria and other substances pernicious to the oral cavity, and the antioxidants present in saliva are among the most important elements that aid in protection against these diseases. Antioxidants present in saliva include uric acid, albumin, ascorbic acid, glutathione and enzymes such as transferrin, lactoferrin and ceruloplasmin [20,13].
