Headgroup effects on phase behavior and interfacial properties of beta-3,7-dimethyloctylglycoside/water systems

The aqueous phase behavior and the interfacial properties of alkylglycosides, AGs, with a 3,7-dimethyloctyl (geranyl) chain have been investigated as a function of the number of glucose units, N, in the maltooligosaccharide headgroup. The results can be interpreted in terms of a "helical conformation" of the maltooligosaccharide, where the cross section area increases as N increases.
