Abstract
Realistic polymer chain models are developed for several polysaccharides to illustrate, using perspective drawings of representative chain conformations, the wide range of configuration, extension, and flexibility found in chains of the polysaccharide class. A method for incorporating the gauche or exo‐anomeric effect into polysaccharide conformational energy functions is described, and a novel measure of directional correlation and pseudohelical persistence is utilized to help distinguish the differences in chain configuration observed among the polysaccharides compared.
