Sugar chains of a major glycoprotein, obtained from the egg jelly coat of a starfish (Asterias amurensis), were released quantitatively as oligosaccharides by hydrazinolysis. After N-acetylation, they were converted to radioactive oligosaccharides by reduction with NaB3H4. Analysis by paper electrophoresis revealed that all of them were neutral oligosaccharides. Upon Bio-Gel P-4 column chromatography, the radioactive oligosaccharide mixture was separated into four components. Structural study of each component by sequential glycosidase digestion in combination with 1H-NMR spectroscopy revealed that the glycoprotein contains the following oligosaccharides, in which R represents either proton, Glc alpha 1----, Glc alpha 1----3Glc alpha 1----, or Glc alpha 1----2Glc alpha 1----3Glc alpha 1----.
