Abstract

A study was conducted to analyze dilute solutions of the ganglioside GM3 in water using small-angle neutron and x-ray scattering techniques. The ganglioside was prepared as sodium salt. Two different wavelengths were utilized to carry out experiments of small-angle neutron scattering. In addition, the Huxley-Holmes camera was used to perform small-angle x-ray scattering. Results indicated thickness fluctuations originating from the mismatch between headgroup and chains lateral hindrances.

Abstract

The issue of the origin of the bending rigidity of a charged membrane formed from amphiphilic molecules is addressed. Electrostatic effects are investigated by direct measurement of the force that is required for deforming a catanionic membrane as function of the ionic strength of the medium by means of an atomic force microscope.
