Primary structure of neutral and acidic oligosaccharide-alditols derived from the jelly coat of the Mexican axolotl : occurrence of oligosaccharides with fucosyl(α1-3)fucosyl(α1-4)-3-deoxy-D-glycero-D-galacto-nonulosonic acid and galactosyl(α1-4)[fucosyl(α1-2)]galactosyl(β1-4)-N-acetylglucosamine sequences

Six major neutral and acidic oligosaccharide-alditols were prepared from the jelly coat of Mexican axolotl eggs. These compounds were demonstrated to contain 3-deoxy-D-glycero-D-galacto-nonulosonic acid (dNloA) and L-fucose (Fuc). The structures of the six major oligosaccharides were established as follows: [sequence: see text]
