N2 - Three trisaccharides, tetra-, penta-, hexa- and certain higher oligosaccharides were obtained from ovine colostrum as free forms. The chemical structure of the three trisaccharides were determined by methylation and 13C-NMR analyses to be as follows: Galα13Galβ14Glc, Galβ13Galβ14Glc (3′-galactosyllactose) and Galβ16Galβ14Glc (6′-galactosyllactose). Galα13Galβ14Glc, which had been confirmed as the oligosaccharide portion of a glycolipid prepared biosynthetically from rat spleen or bone marrow, has been identified for the first time from natural sources as a free form. The trisaccharide containing α-galactosyl unit is a novel compound in mammalian milk.
