Abstract
Asymmetric phospholipid microstructures, such as asymmetric phospholipid membranes, have potential applications in biological and medicinal processes. Here, we used the dissipative particle dynamics simulation method to predict the asymmetric phospholipid microstructures in aqueous solutions. The asymmetric phospholipid membranes, tubes and vesicles are determined and characterized by the chain density distributions and order parameters. The phase diagrams are constructed to evaluate the effects of the chain length on the asymmetric structure formations at equilibrium states, while the average radius of gyration and shape factors are calculated to analyze the asymmetric structure formations in the non-equilibrium processes. Meanwhile, we predicted the mechanical properties of the asymmetric membranes by analyzing the spatial distributions of the interface tensions and osmotic pressures in solutions.
Highlights
Asymmetric microstructures, such as asymmetric membranes, possess asymmetric structures on each side.[1]
We determined the asymmetric membranes, tubes and vesicles for the phospholipid polymers in the phase diagrams in terms of different chain lengths; we focused on the dynamic processes for the asymmetric phospholipid microstructures; we predicted the mechanical properties of asymmetric phospholipid membranes
The asymmetric structures assembled from two types of phospholipid molecules were investigated by analyzing their bead density distributions and order parameters
Summary
Asymmetric microstructures, such as asymmetric membranes, possess asymmetric structures on each side.[1]. Exploring asymmetric phospholipid microstructures with distinct two surfaces is worthwhile
