Screening for the presence of polyglycosylceramides in various tissues: partial characterization of blood group-active complex glycosphingolipids of rabbit and dog small intestines.

abstract：:The rare N-unsubstituted glucosamine (GlcNH (3)(+)) residues in heparan sulfate (HS) have important biological and pathophysiological roles. However, it is difficult to prepare naturally-occuring, GlcNH(3)(+)-containing oligosaccharides from HS because of their low abundance, as well as the inherent problems in both e...
