Polysaccharides of brown seaweeds VII. A comparative study of the products of the smith degradation of pelvecyan and its desulfurated derivative

The fucose residues in pelvecyan are mainly sulfurated and are present on the periphery of a molecule, the nucleus of which consists of a glucuronomannan, The mannose residues are feebly oxidized by periodate and, at least for some of them, this is due not to the presence of sulfate groups but to the nature of the glycosidic linkages in the polysaccharide.
