One electron oxidation of methionine dipeptides (Met-X and X-Met, where X = Gly or Ser) was carried out using the pulse radiolysis technique. It was apparent that the mode of oxidative action of OH radicals on methionine dipeptides was governed by the sequence of amino acids. Spectral evidence suggests that an intramolecular three-electron bond between nitrogen and sulphur atoms is not formed if these two atoms are separated by a peptide bond.
