Figure 3. Kinetics of lipid exchange in different fluid-phase model membranes.

(a) Changes in molar quantities of activation, ΔY^‡, at 37 °C for the Gibbs free energy, ΔG^‡, enthalpy, ΔH^‡, and entropy, −TΔS^‡, as obtained from equations (8) and (9) and data in Supplementary Table 1. (b) Lipid-exchange rate constants, k_obs, as computed on the basis of equation (3) and data in Supplementary Table 2.
