Реферат: The polysaccharide component obtained from the lipopolysaccharide of Shigella dysenteriae type 6 was subjected to mild hydrolysis with acid, and the products were fractionated on Sephadex G-50. An acidic hexosaminoglycan and a core oligosaccharide fraction were obtained, the former containing d-glucose, d-galactose, 2-acetamido-2-deoxy-d-galactose (in the ratios 1:1:1), and an unidentified acidic component (X). The hexosaminoglycan was N-deacetylated and then hydrolysed and deaminated to give 3-O-(2-amino-2-deoxy-β-d-galactopyranosyl)-d-galactose (1), identified as the N-acetyl derivative (2), and 2,5-anhydro-3-O-(6-O-α-d-galactopyranosyl-α-d-glucopyranosyl)talitol (3). On the basis of the structure of 2 and the methylation-analysis data for the polysaccharide and 3, together with that for the determination of linkage configurations by chromic anhydride oxidation, the hexosaminoglycan is considered to have the repeating structure →3)-gb-d-GalNAcp-(1→3)-α-d-Galp-(1→6)-α-d-Glcp-(1→ .
