TLDR
The oxidation of cysteine has been studied at platinum electrodes by chronopotentiometry, polarography, and controlledpotential electrolysis as mentioned in this paper, and the major product was found to be cystine, but the electrode reaction(s) is kinetically complex and is greatly suppressed by the formation of an oxide film or surface oxygen.About:

Higher radical scavenging activities of polyphenolic antioxidants can be ascribed to chemical reactions following their oxidation
TL;DR: A possible mechanism for the oxidation of polyphenols is proposed, in which the oxidizable -OH moieties are reproduced through an oxidative dimerization (or more highly polymerization).

Electrochemical behavior of L-cysteine and its detection at carbon nanotube electrode modified with platinum.
TL;DR: Improved electrochemical behavior of L-cysteine (CySH) on platinum (Pt)/carbon nanotube (CNT) electrode was investigated by cyclic voltammetry and a sensitive CySH sensor was developed based on Pt/CNT/graphite electrode.
