Glycoproteins were isolated from the ovary of the starfish Asterias rubens (L.). After delipidation, sugar analysis revealed the presence of mannose, glucose and N-acetylglucosamine in a molar ratio of 9.0:1.3:2.3. Subsequently, hydrazinolysis, re-N-acetylation, reduction and high-voltage paper electrophoresis were carried out, resulting in a mixture of neutral oligosaccharide alditols which was fractionated on Bio-Gel P-4. The alditols, investigated by 500-MHz 1H-NMR spectroscopy, turned out to be of the oligomannose type or of the gluco-oligomannose type containing 9 mannose and 1-3 glucose residues. The most abundant compounds were established to be: (Formula: see text) and (Formula: see text).
