DPPC bilayers undergo a gel-to-liquid crystalline transition at the main transition temperature 𝑇 𝑚 =314 K. In the liquid crystalline phase, the lipid tails are disordered, in contrast to the gel phase, where the tails are ordered and align parallel to each other. The disordered liquid crystalline phase occurs at higher temperatures and higher equilibrium areas per lipid compared to the gel phase. The gel phase, characterized by highly ordered hydrocarbon chains and restricted molecular mobility, predominates at lower temperatures where entropic contributions to the free energy are minimized relative to cohesive interactions between lipid molecules. These characteristics also result in a higher membrane thickness for the gel phase compared to the liquid crystalline phase. We performed standard DPD simulations of the DPPC membranes in water at different temperatures and at different lateral stretching/compression, determined by the area per lipid in a leaflet.
