In recent years the most significant advances in carbohydrate research have been made in the knowledge of the structure and function of carbohydrates in the macromolecular state. This title addresses those areas of the subject in which the authors believe the most important work is being carried out. Preface (R.J. Sturgeon). Arabinans and arabinan degrading enzymes (G. Beldman et al.). Structural elucidation of the N-linked oligosaccharides of glycoproteins using high pH anion-echange chromatagraphy (K.D. Smith et al.). Neoglycoconjugates as artificial antigens: chemical aspects (N.K. Kochetkov, A.Y. Chernyak). Glycosylation patterns in mucus glycoprotein (A. Slomiany et al.). Index.
