Macromolecular triplex zipping observed in derivatives of fungal (1 --> 3)-beta-D-glucan by electron and atomic force microscopy.


Scleroglucan, a comb-like branched (1 --> 3)-beta-D-glucan, dissolves in water as a stiff, triple-helical structure with the single glucose branches extending from the surface. The aim of this study is to investigate structural changes in the triple-helical structure associated with selective chemical modification of the side chains. Electron and atomic… (More)
