Determination of Complex Carbohydrate Structure Using Carbonyl Carbon Resonances of Peracetylated Derivatives
Oligosaccharides constitute the most abundant and diverse group of compounds present in living systems. Their functions range from that of antigenic determinants, such as the ABO blood-group determinants of man, to the purported regulation of gene expression in plants (Watkins, 1972; Darvill and Albersheim, 1984). Their physiological roles appear to be influenced by their tertiary and, ultimately, their primary structure (Brisson and Carver, 1983; Homans et al., 1986; Carver, 1984; Montreuil, 1980). Their structural complexity arises from the large number of structurally unique residues present and from the variety of ring configurations and of glycosidic linkages that can be made to and from neighboring residues.
