HYDRODYNAMIC PROPERTIES OF CONNECTIVE-TISSUE POLYSACCHARIDES

The major hydrodynamic properties of the connective-tissue polysaccharides are those that describe polysaccharide-water interaction as embodied in their osmotic-pressure and hydraulic-conductivity properties. This study shows that, for polysaccharides such as chondroitin sulphate, hyaluronate and the heparin-like polysaccharides, their hydrodynamic properties depend primarily on the presence of the uronic residue and the nature of the glycosidic linkage. Other parameters such as the degree of N-acetylation and sulphation were found not to influence these properties to any great extent. These studies particularly delineate structural-functional aspects of the connective-tissue polysaccharides in terms of their primary structure.
