摘要
OH redical induced oxidation of methionine and N-phosphoryl methioninein aqueous solutions has been investigated using optical pulse radiolytical technique, theinfluence of N-phosphoryl group on the radiolytical processes of methionine has beenexplained by molecular structure and the rate constants of oxidation of N-phosphoryl methionine (NDM) by the OH radicals at different pH values have been determined. Thisresearch result suggests that the phosphonate ester has a coordinating effect on the radioprotection of methionine to the biological systems.
