Snapshots of (A) a constrained DMPC lipid and (B) a DPPC lipid at different locations relative to the center of the membrane.

Abstract

Each color represents the configuration of the lipid at a different time, taken from the last 5 × 105 time steps and separated by 5 × 104 time steps. The overlaying of the configurations illustrates the flexibility and orientation of the constrained lipid molecule. Head groups and tails of the lipid are represented by thick and thin bonds, respectively.</p
