Glycosaminoglycans (GAGs) from the hemolymph of the freshwater snail Planorbarius corneus were recovered at about 0.9 µg/mL, being composed of a unique species characterized as chondroitin sulfate (CS) with a molecular mass of approx. 31,000 and having glucuronic acid as hexuronic acid. This macromolecule was determined to be composed of a low-sulfated polysaccharide made up of approx. 25% of the nonsulfated disaccharide, 17% of the 6-sulfated disaccharide, and about 58% of the 4-sulfated disaccharide, with a charge density value of 0.75 and a 4-sulfated/6-sulfated ratio of approx. 3.4. The data obtained suggest that the CS recovered in the Planorbarius corneus hemolymph is similar to the main human plasma polysaccharide and it may be generated as a main product of the catabolic processes.

Abstract
Glycosaminoglycans (GAGs) from the hemolymph of the freshwater snail Planorbarius corneus were recovered at about 0.9 µg/mL, being composed of a unique species characterized as chondroitin sulfate (CS) with a molecular mass of approx. 31,000 and having glucuronic acid as hexuronic acid. This macromolecule was determined to be composed of a low-sulfated polysaccharide made up of approx. 25% of the nonsulfated disaccharide, 17% of the 6-sulfated disaccharide, and about 58% of the 4-sulfated disaccharide, with a charge density value of 0.75 and a 4-sulfated/6-sulfated ratio of approx. 3.4. The data obtained suggest that the CS recovered in the Planorbarius corneus hemolymph is similar to the main human plasma polysaccharide and it may be generated as a main product of the catabolic processes.
