[Further biochemical investigations on glycosaminoglycans extracted from Euglena gracilis].

Polyanionic glycans extracted from Euglena gracilis have been studied by biochemical, chromatographic and electrophoretic analysis. Our results show the presence of a fraction which precipitate with CPC and another one which not precipitate with CPC. The CPC precipitable material fractionated on CPC-Cellulose column shows the presence of 5 Glycosaminoglycans; the not CPC precipitable material contains uronic acid, galactose, sulfate, galactosamine and cannot be related to Keratan sulfate.
