Such a situation is rather common for D-galactose and the structurally related monosaccharides L-arabinose218 and D-fucose thus far, the latter monosaccharide has been identified only as the furanose form in the O-specific polysaccharide of Eubacterium saburreum.219 6-Deoxy-L-altrose is present as the pyranose in the lipopolysaccharide of Yersinia enteroco-litica,20 but as the furanose in a similar polymer220 of Y. pseudotuberculosis type VB. Paratose, which is usually present in polysaccharides as the a-pyranose, was identified as the /3-furanose in the O-specific polysaccharide221,222 of Y. pseudotuberculosis serotype IB.
