  Determination of 3-O- and 4-O-methylated monosaccharide constituents in snail glycans

  摘要：

  The N- and O-glycans of Atlanta arbustorum, Achatina fulica, Anion lusitanicus and Planorbarius corneus were analysed for their monosaccharide pattern by reversed-phase HPLC after labelling with 2-amino-benzoic acid or 3-methyl-1-phenyl-2-pyrazolin-5-one and by gas chromatography-mass spectrometry. Glucosamine, galactosamine, mannose, galactose, glucose, fucose and xylose were identified. Furthermore, three different methylated sugars were detected: 3-O-methyl-mannose and 3-O-methyl-galactose were confirmed to be a common snail feature: 4-O-methyl-galactose was detected for the first time in snails.

  The four tri-O-benzyl ethers of benzyl α-D-galactopyranoside were prepared from benzyl 6-O-allyl-α-D-galactopyranoside. The stability of 4,6-O-propylidene derivatives of benzyl-α-D-galactopyranoside in acidic hydroxylic solvents was noted in this work.
