Trapping Method

The radicals produced during γ radiolysis of methanol, ethanol, 1-propanol, 2-propanol, and t-butanol have been trapped by reaction with 2-nitroso-2-methylpropane (t-nitrosobutane) to give nitroxides which are detected by e.s.r.[Formula: see text]All the alcohols gave alkoxy radicals and, with the exception of t-butanol, radicals derived by the loss of an H atom from the carbon atom adjacent to the OH group. Methyl radicals were detected in t-butanol.

The electron spin resonance spin-trapping method has been used for detection of radicals in human low density lipoprotein (LDL) solution saturated with oxygen. The trapped radicals could be detected after about a day in an antioxidant-free solution. Two types of radicals are formed and stabilized in the lipid domain of LDL. The nature of the trapped radicals remains unclear:kinetic considerations suggest the trapped radicals to be of the LO- type, while the spectroscopic parameters are in favour of L- type radicals.
