Table 2.
Lipid areas A (Å2) as a function of temperature, hydrocarbon chain length, and the degree of hydrocarbon chain unsaturation. Lipid area thermal and chain length expansivities, αTA and αncA, respectively, are also shown. αncA 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).
