Abstract
The structure of sulfated oligosaccharide II, one of the main sulfated oligosaccharide chains of ovomucin, has been determined. This oligosaccharide was found to compose of each 1 mole of N-acetylgalactosaminitol, galactose, N-acetylneuraminic acid and sulfate. The sequential periodate oxidation, borohydride reduction and acid hydrolysis of N-acetylneuraminic acid-free oligosaccharide resulted in the formation of glycerol and N-acetylthreosaminitol.
From these results, the following structure was proposed for sulfated oligosaccharide II: N-acetylneuraminyl-(2→3)-galactosyl-(1→3)-N-acetylgalactosaminitol-6-sulfate.
