title: Polarized infrared spectra of crystalline glycosaminoglycans.
abstract: Polarized infrared spectra have been recorded for oriented, crystalline specimens of hyaluronates, chondroitin 4-sulfate and 6-sulfate, dermatan sulfate, and a cartilage proteoglycan, having different known chain conformations as determined by X-ray diffraction. The dichroism data for the vibrational modes of the amide and carboxyl groups have been interpreted with respect to the particular molecular structures.
