Treatment of sialoglycopeptides derived from bovine milk-fat-globule membrane with alkaline borohydride released a reduced oligosaccharide fraction from which a tetrasaccharide and two trisaccharides were isolated. Periodate-oxidation studies coupled with methylation analysis and g.l.c.-mass spectrometry established their structures as: N-acetylneuraminyl-(2 leads to 3)-beta-D-galactopyranosyl-(1 leads to 3)-[N-acetylneuraminyl-(2 leads to 6)]-N-acetyl-D-galactosaminitol, N-acetylneuraminyl-(2 leads to 3)-D-glactopyranosyl-(1 leads to 3)-N-acetyl-D-galactosaminitol and beta-D-galactopyranosyl-(1 leads to 3)-[N-acteylneuraminyl-(2 leads to 6)]-N-acetyl-D-galactosaminitol respectively.
