ABSTRACT

The structure of four oligosaccharides which are the main carbohydrate chains of hemagglutinin of influenza virus A/Leningrad/385/80 (H3N2) has been elucidated. It was shown by means of enzymatic and mild acid hydrolysis, Smith degradation and acetolysis that the oligosaccharides have very similar structures (noncomplete triantennary) and differ from each other only in the number (0, 1 or 2) and position of fucose residues. The peculiarities of glycosylation of H3 hemagglutinin from different strains of influenza virus were discussed.
