title: 500 MHz 1H n.m.r. of oligosaccharides of N-acetyl-lactosamine-type released from human erythrocyte glycopeptides by endo-beta-galactosidase.
abstract: 500 MHz 1H n.m.r. spectroscopy has been used in structural studies of three linear and five branched oligosaccharides of N-acetyl-lactosamine-type that were released from desialylated blood group O erythrocyte glycopeptides by treatment with the endo-beta-galactosidase of Bacteroides fragilis followed by reduction. The following oligosaccharide alditols were characterized: (formula; see book)
