[Gas chromatographic mass spectrometric analysis of neurtral and acid oligosaccharides from human milk as their trimethylsilyl derivatives (author's transl)].
Gas chromatography and the 20 eV mass spectra of the human milk oligosaccharides fucosido-galactose, fucosido-lactose, di-fucosido-lactose, 3'-N-acetylneuraminyl-lactose, 6'-N-acetylneuraminyl-lactose and of N-acetyllactosamine as pertrimethylsilyl (TMS) ethers are described. The gas chromatographic separation of the L-fucose containing oligosaccharides was performed on Silicone SE 30. The sialic acid containing sugars were separated on DEXSIL 300. The correlations between oligosaccharide structures and mass spectrometric fragmentation patterns are discussed.
