1. Methods have been described for reducing protein S-S groups, for oxidizing protein SH groups, and for estimating protein S-S and SH groups. 2. It has been found necessary in estimating the cystine content of proteins by the Folin-Marenzi method to take into account any cysteine that may be present. 3. A method for estimating the cysteine content of proteins has been described. 4. With these methods, estimations have been made of the S-S and SH groups and of the cystine and cysteine contents of a number of proteins. 5. In a denatured, but unhydrolyzed protein, the number of S-S and SH groups is equivalent to the quantity of cystine and cysteine found in the protein after hydrolysis.
