✦ Synopsis

The biologically very important cysteine (RSH))cystine (RSSR) system has been the subject of many investigations, including polarographic studies and amperometric titrations'J. The very simple polarographic method permits the simultaneous determination of both compounds; at positive potentials of the dropping mercury electrode, RSH undergoes the following anodic reaction:
