Title : Structure of four acidic oligosaccharides from the jelly coat surrounding the eggs of Xenopus laevis

Abstract :
  1. Novel acidic oligosaccharides were released by reductive beta-elimination from the jelly coat eggs of the Anuran Xenopus laevis
  2. 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.
  3. 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
