The electrochemistry of l-cystine and l-cysteine: Part 1: Thermodynamic and kinetic studies
TL;DR: In this article, thermodynamic and kinetic aspects of the electrochemistry of l -cystine reduction and l-cysteine oxidation are reviewed both mercury and a range of solid electrodes are considered.

The electrochemistry of proteins and related substances: I. Cystine and cysteine at the mercury electrode
TL;DR: In this article, the electroreduction of cystine (RSSR) and oxidation of cysteine (RSH) at several pH's at a hanging Hg drop electrode by cyclic voltammetry and at a Hg pool by coulometry are described.

Cathodic stripping voltammetry: Part I. Determination of organic sulfur compounds, flavins and porphyrins at the sub-micromolar level
TL;DR: In this article, the experimental parameters of cathodic stripping voltammetry have been studied and optimised, and the use of a cell with a mercury pool electrode has been proposed, which is valuable for the determination of several classes of organic compounds, including thiols, disulfides, flavins, flavones, pterins and porphyrins.
Journal ArticleDOI
The reactions of cystine at mercury electrodes
TL;DR: In this article, the potential of a partially free mercury surface in a currentless process and at an occupied electrode under the passage of current was made less positive, and two electrons were transferred directly to the cystine SS bond in an overall irreversible process.
Journal ArticleDOI
The electrochemistry of proteins and related substances: Part II. Insulin
TL;DR: The electroreduction of insulin in pH 7.4 solution was studied at the hanging mercury drop electrode by cyclic voltammetry and at a mercury pool electrode by controlled potential coulometry as discussed by the authors, and the proposed mechanism involves reduction of an adsorbed monolayer of insulin (maximum coverage of 10 μC cm−2) in a fourelectron reaction at about −0.6 V vs. SCE resulting in breakage of two of the three disulfide bonds in the molecule.
