can amide group undergoes oxidation with hydrogen peroxide at room temperature to yield nitro group ??
if yes what is the suggested mechanism?? as i added 0.5 ml of hydrogen peroxide (30 %) to 10 ml aqueous solution of amino acids containing structure left it at room temperature for 72 hours , then freeze dried the aqueous solution and analysed the resullted solid by IR, the IR frequencies showed two new strong bands at 1587.42 and 1398.36 than the IR of the intact structure before oxidation, thanks in advance0

it is a peptide chain with amino acid sequence of arginine- glycine-aspartic acid- tryptophan-proline-cysteine-mercaptopropionic acid linked together with amide linkage and disulphide bridge,
in the intact structure there was two bands in this region one at 1656 and another one as a shoulder of the previous band at 1543 cm-1 , one another small band at 1402 cm-1 then in the oxidized product the band at 1656 cm-1 vanished and one broad band evolved at 1587 cm-1 and another less broad one at 1398 cm-1, what could be the cause??
