Title : Structural analysis of oligosaccharide-alditols released by reductive beta-elimination from oviducal mucins of Bufo bufo: characterization of the carbohydrate sequence Gal(alpha1-3)GalNAc(alpha1-3)[Fuc(alpha1-2)]Gal

Abstract :

1. Several tri- to hexasaccharide-alditols of the jelly coat surrounding the eggs of Bufo bufo were studied by methylation analysis, MALDI-TOF mass spectrometry, and 1H-NMR spectroscopy
2. As observed for six other amphibian species, these carbohydrate chains are highly species-specific
3. The main characteristics of the species Bufo bufo consists in the presence of the new carbohydrate sequence Gal(alpha1-3)GalNAc(alpha1-3)[Fuc(alpha1-2)]Gal, in which a blood group A determinant is substituted with an external alpha1-3 linked galactose unit
4. Since the role of carbohydrates appears more and more apparent during the fertilization processes, the species-specificity of these carbohydrate moieties should be relevant to the species-specific gamete recognition which characterizes most amphibians
