Thiolated gelatin

It may seem odd that the technique of spectrophotometric titration, so extensively applied to the tyrosyl residues of proteins, has not been used in the study of protein sulfhydryl groups. The only study of this sort known to the author is the determination of the ionization constant of —SH grouj of thiolated gelatin (introduced by reaction with A -acetylhomocysteine thiolactone). By measuring the change in absorptivity as a function of pH at 2380 A, Benesch and Benesch (1958) found the apparent acidity of the thiol groups of the modified gelatin (pK = 9.8) to be nearly the same as that of an appropriate model compound, A -acetylhomocysteine (pK = 10.0). [Pg.339]
