${\eta }_{\text{Ld}}$s for compositions a, b, and c, ${\eta }_{\text{DOPC}}$, and ${\eta }_{\text{DPPC}/\text{CHOL}=1:1}$ as a function of the temperature. Solid lines denote the fitting results by ${\eta }_{\text{Ld}}=A\exp \left(B/T_{\text{abs}}\right)$, where $A$ is the numerical constant, $B$ is the slope of the temperature dependence of membrane viscosity, and $T_{\text{abs}}$ is the absolute temperature. The temperature dependence of ${\eta }_{\text{DOPC}}$ has a steep slope compared to the other compositions. The black solid line and dashed line denote the calculated ${\eta }_{\text{Ld}}$ by simply taking the weighted average of the DPPC/CHOL complex and DOPC and the MH model, respectively. The error bars express mean ± SE.
