Abstract

The local structure of a GM3 ganglioside bilayer, whose wide-angle X-ray spectrum is reconstructed from molecular dynamics simulations, is found to compare quantitatively well with the experimental one. By separating inter- and intramolecular contributions, correlations between distinct head groups are shown to contribute in a substantial way to the total scattering intensity. This finding supports the hypothesis of a strong local head group order as recently formulated on the basis of calorimetry and X-ray experimental data.
