Abstract:
The glycosaminoglycan (GAG), isolated from Bay scallop Argopectenirradians, contains neutral monosaccharides besides hexosamines and hexosuronic acids. The monosaccharides obtained by alcoholysis with HCI-methylalcohol from the sample of GAG was trimethylsilanized with hexamethyldisilan and chlortrimethylsilan (HMDS ' TMCS = 2 : 1). And the trimethylsilyl derivatives of monosaccharides was determined by gas chro-matography. Compared the gas chromatography of the sample with that of standard monosaccharides, it was found that the GAG of the Bay scallop contains five neutral monosaccharides, viz glucose, galactose, xylose, fucose and rhamnose.
