THE IODOMETRIC DETERMINATION OF CYSTlNE IN THE URINE

The iodometric titration of thiol compounds, first introduced by Rosenheim and Davidsohn (1) and modified by Klason and Carlson (2), was applied to the determination of cysteine and related compounds by Okuda, who studied the reaction of cysteine with iodine in acid solution (3). The reaction would be a valuable one if the conditions for the conversion of -SH to -SS(cysteine to cystine) could b...

The Iodometric Determination of Cysteine* by Theodore F. Lavine

Lucas and King (1) and Virtue and Lewis (2) have recently proposed essentially similar methods for the estimation of cysteine, wherein an excess of iodine is back titrated at 0” in N HCI, as being a more satisfactory procedure than that of Okuda (3), since under their conditions the theoretical equation for the oxidation of -SH to -S-Scan be used. However, even at 0” the excess of I, present, a...
