Title : Structure of
four acidic oligosaccharides from the jelly coat surrounding the eggs of Xenopus laevis
Abstract :
- Novel acidic oligosaccharides were released by reductive beta-elimination from the jelly coat eggs of the Anuran Xenopus laevis
- According to the structural analysis of these oligosaccharide-alditols , the following structures are proposed: [sequence: see text] where Kdn, 3-deoxy-D-glycero-D-galactononulosonic acid.
- These results confirm the species specificity of the glycanic structures present in the secretion of amphibian oviducts, and may form the basis of a specific egg-sperm recognition process
