Graphic abstract: NMR study of thiosulfate-assisted oxidation of L-cysteine

Abstract: The reaction of L-cysteine with sodium thiosulfate in aqueous solution at pH 9 affords mainly L-cystine with noticeable amounts of L-cysteine sulfonic anion ^–O₂CCH(NH⁺)CH SO^–. NMR study revealed the formation of intermediate L-cysteine sulfenic acid and L-cysteine S-sulfite, the latter existing in two active forms ^–O₂CCH(NH₂)CH₂S(=S)O^– and ^–O CCH(NH)CH SSO^–.

Keywords: oxidation, L-cysteine, L-cystine, thiosulfate, L-cysteine S-sulfite, L-cysteine sulfenic acid, thiols, disulfides, NMR study.
