title: Water vapor sorption of keratan sulfate.
abstract: Keratan sulfate was isolated from bovine cornea. The water vapor sorption isotherms were obtained on both sodium and calcium salts of keratan sulfate at different temperatures. Deuterated water sorption isotherms were obtained on sodium keratan sulfates. The infrared spectra of the keratan-sulfate was monitored as a function of water and D2O uptake. The results are discussed in terms of an open polymer matrix that exists in the solid state of keratan sulfate.
