A Brownian dynamics simulation of an acyl chain and a molecule confined in a phospholipid bilayer in the gel and liquid crystal phases

Article Abstract:

A Brownian dynamics simulation of a saturated 16 C atom acyl chain, in an environment that reproduces a phospholipid bilayer in the gel phase, is presented. The simulations of t-PnA, a fluoresent fatty acid widely used to probe lateral lipid domains in bilayers and membranes, reinforces the validity of the mean-field description.

Molecular dynamics simulations of ubiquinone inside a lipid bilayer

Article Abstract:

A series of multiple nanosecond molecular dynamics simulations is carried out for a dipalmitoylphosphatidycholine lipid bilayer system in water solution, with ubiquinone (UQ) freely moving inside the bilayer. The mobility and the preferential positions of the quinone molecule are studied.

Influence of lipid chemistry on the osmotic response of cell membranes: effect of non-bilayer forming lipids

Article Abstract:

The effect of four non-bilayer forming lipids on the stability of phosphatidylcholine (PC, a bilayer forming lipid) membranes is examined. Large unilamellar vesicles were subjected to hypo-osmotic gradients and the leakage of their contents was quantified.
