“…However, in the presence of oxygen the reaction between thiyL radical and O 2 (reaction 8; k 8 = 2.2 × 10 9 M −1 s −1 34) could yield a thiyLperoxyl radical (RSOO · ) prior to recombination with the second thiyL radical (reaction 9). The bis(alkylthio)peroxide, RSOOSR, produced in reaction 9 is characterized by a very weak O—O bond energy,35 suggesting that it suffers spontaneous homolytic cleavage into two sulfinyl radicals (reaction 10). …”

“…It should be pointed out that acetaldehyde was produced instead (see the section Analysis of Stable Products). Since sulfenic acids (RSOH) undergo readily hydrogen atom abstraction to fairly stable sulfinyl radicals (RSO•), such abstraction reaction by acyl radicals to yield acetaldehyde is thermodynamically possible (Scheme , reaction 1g). Theoretical calculations at the PM3 level predict a 74 kcal mol -1 value for the RSO−H bond dissociation energy (BDE) .…”

“…1 The consequences of such oxidations are numerous. Among the main targets of these free radicals are Methionine (Met) residues [2][3][4][5][6][7][8][9] which can be implicated in neurodegenerative diseases as well as in the ageing processes. Their oxidation by…”

“…The consequences of such oxidations are numerous. Among the main targets of these free radicals are methionine (Met) residues which can be implicated in neurodegenerative diseases as well as in the aging processes. Their oxidation by · OH has been the focus of numerous experimental and theoretical studies these past 30 years.…”
