Kinetic and Mechanistic Studies of Peroxy, Vitamin E and Anti-Oxidant Free Radicals by Pulse Radiolysis

  • Michael G. Simic


Autoxidation processes in food and biological systems are based on free radical reactions which involve a variety of organic peroxy radicals, ROO·, oxy radicals, RO· and superoxide radical (sometimes also called perhydroxyl radical), ·O2 + H+ ⇋ ·O2H. As indicated, the superoxide radical comes in two forms: (a) the anionic form, ·O2 , which is present predominantly in solutions with pH above pKa = 4.8, and (b) the protonated form, ·O2H, which is present predominantly in the solutions with pH below the pKa value and in less polar media.
