Notes:
The O-trimethylsilyl derivatives of five reference disaccharide alditols composed of a N-acetylhexosaminitol substituted at C-3, C-4 or C-6 with a hexose moiety were studied by gas chromatography mass spectrometry. The data were used in the determination of the linkage in disaccharide alditols derived from rat brain glycoproteins and gangliosides. The O-glycosidically linked carbohydrate units of brain glycoproteins contained two oligosaccharides, β-galactosyl-(1 → 3)-N-acetylgalactosaminitol and α-galactosyl-(1 → 3)-N-acetylgalacto-saminitol, whereas only the latter was obtained from brain gangliosides after partial acid hydrolysis and reduction.
