Galactose-6-sulfate and N-acetylglucosamine-6-sulfate were obtained pure from a partial acid hydrolyzate of corneal keratosulfate by paper chromatography and electrophoretic fractionation. These sugars were also present in hydrolyzates of skeletal keratosulfate. The distribution of the sulfate groups in the various keratosulfates might depend upon their source, and this distribution probably has important biological significance.
