A molecular view of cholesterol-induced condensation in a lipid monolayer

Article Abstract:

The intermolecular interactions in a mixed phospholipid/cholesterol monolayer are investigated using the surface specific technique of vibrational sum frequency generation. The technique enables to monitor the conformational and orientational order in the phospholipid as the surface pressure and cholesterol content are varied.

Effect of the choice of the pressure coupling method on the spontaneous aggregation of DPPC molecules

Article Abstract:

The self-assembly of DPPC lipid molecules starting from a random, solution-like configuration in the presence of water molecules is described. Simulating the same system with isotropic pressure coupling led to the formation of a cylindrical micelle/lamellar structure with a large water hole.
