Primary structure of acidic oligosaccharide-alditols derived from the jelly coat of Ambystoma tigrinum. Occurrence of oligosaccharides with fucosyl(alpha 1-5)[fucosyl(alpha 1-4)]-3-deoxy-D-glycero-D-galacto- nonulosonic acid and fucosyl (alpha 1-2) galactosyl (alpha 1-3)-N- acetylgalactosamine sequences.
Eleven O-glycosidic carbohydrate units derived from the jelly coat of Ambystoma tigrinum were analyzed by 1H-NMR spectroscopy. As previously shown for four other amphibian species, the glycans display a remarkable species specificity. As a characteristic feature, 3-deoxy-D-glycero-D-galacto-nonulosonic acid (Kdn) was found difucosylated at C4 and C5, and alpha-Gal attached to C3 of GalNAc-ol. The most representative carbohydrate units are: [formula: see text]
