ABSTRACT
The reaction between the phenoxyl radical of Trolox C, a water-soluble vitamin E analogue, and superoxide anion radical was examined by using the pulse radiolysis technique. The results indicate that the Trolox C phenoxyl radical may undergo a rapid one-electron transfer from superoxide radical [k = (4.5 +/- 0.5) x 10(8) M-1.S-1] to its reduced form. This finding indicates that superoxide radical might play a role in the repair of vitamin e phenoxyl radical.
