Glucan derivatives, structural complexity

Benzyl derivatives of (1 6)-a-D-glucan, (l->6)-a-D-mannan, and (l-> 6)-a-D-galactan have been studied in 1,4-dioxane. These derivatives have complex and interesting c.d. spectra due to the ww transition of the chromophore with resolved vibrational structure. However, a conformational interpretation of these interesting spectra is not possible at this time. 

The complexity of glucan derivatives and the structural parameters of influence on the reactivity and properties of products have now been outlined. Next discussed is how this challenging complexity is faced and handled in analysis. Concepts and experimental approaches to achieve quantitative information on various stmctural levels and interpretability of experimental data are also discussed.
