Cysteine was discovered indirectly in 1810 by Wollaston, who isolated a crystalline substance from urinary calculi (kidney stones) and called it “cystic oxide” (Vickery and Schmidt, 1931). We now know this substance as cystine, the oxidised dimeric form of cysteine, and the first amino acid to be discovered. As a building block of proteins, however, cysteine (in the form of cystine) evaded detection for several decades, probably because the early methods of amino acid analysis were incompatible… Expand
