Effect of ST on the LPPs of model LDs in CG-SDK simulations. (Top) Snapshot of an LD interface. (Bottom) Lateral pressure as a function of the ST. The positive peak between the polar heads of phospholipids (I) is not affected by ST, whereas major changes can be observed in the negative attractive peak at the hydrophilic/hydrophobic interface of POPC molecules (II). Also, variations in height and shape can be observed in the positive peak between the POPC acyl chains and the TO molecules (III), in particular for values >10 mN/m (purple and red lines). The integral of this peak (inset) is quite constant for low ST but shows a substantial decrease from 10 mN/m to higher STs. The LPP of a TO/W interface using the CG model is shown for comparison.
