THE ACTION OF MERCURIC SULFATE AND CHLORIDE ON CYSTEINE, CYSTINE, CYSTEINE SULFINIC ACID (R—SO2H), AND CYSTEIC ACID WITH REFERENCE TO THE DISMUTATION OF CYSTINE

The Action of Mercuric Sulfate and Chloride on Cysteine, Cystine, Cysteine Sulfinic Acid (r-so~h), and Cysteic Acid with Reference to the Dismutation of Cystine*

Preceding studies (1) show that one of the products of the dismutation of cystine disulfoxide (R-(SO)z-R) is the sulfinic acid (R-SOZH), a compound which possesses greater stability in solution than any other intermediate oxidation product of cystine obtained thus far. It was interesting, therefore, to determine whether the sulfinic acid results from the dismutation of cystine in the presence o...

On the Determination of Cystine as Cysteic Acid

In the procedure of Schram, Moore, and Bigwood (1) for the determination of the cystine plus cysteine content of a protein, the directions for the concentration of the reaction mixture need to be followed explicitly in order to avoid overoxidation. The addition of a reducing agent to destroy the excess performic acid before the concentration step would seem appropriate if the reductant would ha...

The Photometric Determination of Cystine , Cysteine , Ascorbic Acid , and Related Com - Pounds with Phosphotungstic Acid

Some time ago a brief report (1) was made on the use of the Pulfrich photometer for the determination of sulfhydryl and disulfide compounds by a modified Folin (2) method. Since then the method has been extensively used in this laboratory (3-9). Folin’s method is based upon the observation that cystine plus sulfite gives a blue color with phospho-18-tungstic acid; whereas cystine alone develops...
