title: Structures of the alpha(1-3)-galactose-containing asparagine-linked glycans of a Lewis lung carcinoma cell subline resistant to Aleuria aurantia agglutinin: elucidation by 1H-NMR spectroscopy.
abstract: Four bi-antennary glycan fractions of the N-acetyllactosamine-type, derived from a Lewis lung carcinoma (LL2) cell subline resistant to the Aleuria aurantia agglutinin were studied by 400 MHz 1H-NMR spectroscopy. By this method, their antennae were found to be terminated either by alpha(2-3 or 6)-linked N-acetylneuraminic acid or alpha(1-3)-linked galactose residues. The primary structure of glycans of these four glycopeptide or derived oligosaccharide-alditols has been determined in full detail.
