WebNov 11, 2015 · Cysteine is a potent chelator of heavy metals ions, but cysteine-metal ion complexes can trigger the Fenton reaction, thereby producing the highly toxic ⋅ OH radical. Furthermore, free cysteine is often irreversibly oxidized to different by-products [ 19] and reversibly to cystine (cysteine disulphide).
