Table 3.

Overall bilayer thicknesses D_B (Å) as a function of temperature, hydrocarbon chain length, and the degree of hydrocarbon chain unsaturation. Overall bilayer thickness thermal contractivities and chain length expansivities, α^T_DB and α^nc_DB, respectively, are also shown. α^nc_DB is calculated for each group of lipids depending on their total number of double bonds (e.g., 0 for DLPG, 1 for POPG, and 2 for DOPG).
