Structure of three Kdn-containing oligosaccharide-alditols released from oviducal secretions of Ambystoma tigrinum: characterization of the carbohydrate sequence Fuc (alpha 1-5) [Fuc (alpha 1-4)] Kdn (alpha 2-3/6).
Oligosaccharide-alditols released by reductive beta-elimination from the egg jelly coat of Ambystoma tigrinum were analyzed by 1H NMR spectroscopy. As observed for five other amphibian species, these carbohydrate chains are highly species-specific, and should support the species-specificity of gamete interaction. The carbohydrate chains of Ambystoma tigrinum are characterized by the presence of a new type of sequence: Fuc (alpha 1-5) [(Fuc (alpha 1-4)] Kdn (alpha 2-3/6).
