In the radiolysis of oxygenated aqueous solutions of cysteine (RSH) at pH 7, short chain reactions occur yielding cystine (RSSR) and hydrogen peroxide. Two competing reaction paths involving reaction of the thiyl radical (RS•) with oxygen or thiol anion (RS − ) are postulated to explain the results.
