Snail galactans are highly branched polysaccharides which are synthesized in the albumen glands of pulmonate and prosobranchiate snails and added to the perivitelline fluid of their eggs as nutritive material for the growing embryos. (1) Snail galactans are predominantly composed of D Galactose linked glycosidically l→3 and l→6 (2,3). Depending on the species additional constituents were described, such as Lgalactose in Helix pomatia, Arianta arbustorum or Capaea nemoralis (14%), L fucose in Ampullarius spec. (2%) (4) or phosphate groups as in H. pomatia, C. nemoralis and in Biompholario glabrata (2%) (3).
