title: Structural determination of monosialyl trisaccharides obtained from caprine colostrum.
abstract: Acidic oligosaccharides were separated by dialysis, ion-exchange, preparative paper and gel chromatography from caprine colostrum. Four sialyl trisaccharides were characterized by 1H-NMR spectrometry as follows: alpha-N-acetylneuraminyl-(2,6)-beta-D-galactopyranosyl-(1,4)-2-N-acetami do-2 -deoxy-D-glucopyranose (Neu5Ac alpha 2-6Gal beta 1-4GlcNAc), alpha-N-acetylneuraminyl-(2,3)-beta-D-galactopyranosyl-(1,4)-D-glucopyra nose (Neu5Ac alpha 2-3Gal beta-1-4Glc), alpha-N-acetylneuraminyl-(2,6)-beta-D-galactopyranosyl-(1,4)-D-glucopyra nose (Neu5Ac alpha 2-6Gal beta 1-4Glc) and alpha-N-glycolylneuraminyl-(2,6)-beta-D-galactopyranosyl-(1,4)-D -glucopyranose (Neu5Gc alpha 2-6Gal beta 1-4Glc).
