Copper(II)-albumin complex can activate hydrogen peroxide in the presence of biological reductants: first ESR evidence for the formation of hydroxyl radical.

Abstract

Copper(II)-albumin complex did not directly react with hydrogen peroxide (H2O2). However, Cu(II)-albumin complex was easily reduced to Cu(I) complex by some biological reductants such as L-cysteine and L-ascorbic acid. Cu(I) complex thus formed could react with H2O2 to give hydroxyl radical (.OH) which was detected by electron spin resonance (ESR… (More)
