    Abstract:
    The structure of a nonasaccharide and of two decasaccharides isolated from human milk has been investigated by using methylation, fast atom bombardment mass spectrometry and 1H-/13C-nuclear magnetic resonance spectroscopy. The structures of these oligosaccharides were: trifucosyllacto-N-hexaose; Fuc alpha 1-2Gal beta 1-3(Fuc alpha 1-4)GlcNAc beta 1-3[Gal beta 1-4(Fuc alpha 1-3)GlcNAc beta 1-6]Gal beta 1-4Glc, difucosyllacto-N-octaoses; Gal beta 1-3(Fuc alpha 1-4)GlcNAc beta 1-3Gal beta 1-4(Fuc alpha 1-3)GlcNAc beta 1-6[Gal beta 1-3GlcNAc beta 1-3]Gal beta 1-4Glc and Gal beta 1-3GlcNAc beta 1-3Gal beta 1-4(Fuc alpha 1-3)GlcNAc beta 1-6[Fuc alpha 1-3 Gal beta 1-3GlcNAc beta 1-3]Gal beta 1-4Glc. The two decasaccharides possess a new type of core structure proposed to be named iso-lacto-N-octaose.
