Concentrations (C_α) of and correlations (C_αβ) between different molecule types. (a) Simulation snapshot of 216 liquid-water molecules at 1 atm and 300 K, where the green, white, and red spheres represent the LDL, HDL, and UHDL molecules, respectively. These molecules are labeled according to their inherent local structures. Panels (b) and (c) show, respectively, the temperature dependence of C_α and C′αU=CαU/CU at 1 atm, as given by the 216-molecule simulations.
