Free radical reactions of lysozyme (Lz), tryptophan and disulfides were studied with curcumin, a lipid-soluble antioxidant from turmeric, in aqueous solution using a pulse radiolysis technique. The binding of curcumin with lysozyme was confirmed using absorption, fluorescence and stopped-flow techniques. The free radicals of curcumin generated after repairing radicals of disulfides, lysozyme and tryptophan absorb at 500-510 nm. Implication of this in evaluating the antioxidant behavior of curcumin in protecting proteins is discussed.
