摘要

Glycosaminoglycan (GAG) was extracted from monkey periodontium, consisting of gingiva, periodontal ligament, alveolar bone and cementum, and from dental pulp and dentin by digestion with Pronase E. Unsaturated disaccharide isomers formed by chondroitinase AC digestion from chondroitin sulfate were labeled with dansylhydrazine and analyzed by high-performance liquid chromatography. These tissues showed different molar ratios of the unsaturated chondroitin sulfate disaccharides. The ratio of delta Di-4S to delta Di-6S was lowest in the dental pulp, followed by the gingiva, periodontal ligament, dentin, alveolar bone, and cementum, in that order. It was greater in the calcified than in the uncalcified tissues.
