MS spectra of GSH-NEM derivatized (m/z 433.14) obtained after exposure of GSH (500 uM) to AAPH (2 mM) at 37 °C during 1 hour in H2O-buffer (A) and D2O-buffer (B). The table summarizes the percentage of GSH-NEM derivatized molecules having incorporated covalently one deuteron atom after reaction of GSH with AAPH at different pH/pD in H2O/D2O-buffers.
