Free methionine is readily oxidized to methionine sulfoxide by many reactive oxygen species, including the two-electron acceptor hydrogen peroxide, as shown here.

MET + HYDROGEN-PEROXIDE --> L-Methionine-sulfoxides + WATER

L-Methionine[C5H11NO2S] + Hydrogen peroxide[H2O2] = L-Methionine S-oxide[C5H11NO3S] + H2O[H2O]
