Abstract

Abstract: The formation mechanism and subsequent reaction of anion radical of VK₃, hasbeen investigated using pulse radiolysis technique.It has been observed that the anion radicalof VK₃, with the maximum absorption peak round 340 nm is different from that with the max-imum absorption at 390 nm observed by others, the reasons of this difference has been ini-tially analysed.This paper also explores the protection action of VK₃, to some bases of DNA,showing that VK₃, itself is a good radiation protector.

Key words: Vitamin K, Electron transfer, Base, Radiation protection, Pulse radiolysis
