Geometric Properties of MLCL and TOCL

	Area per Lipid (Å2)	Area per Acyl Chain (Å2)	Hydrophobic Thickness (Å)	Interdigitation (Å)	c0 (1/Å)
TOCL	129.0 ± 0.3	32.2 ± 0.1	30.9 ± 0.1	5.49 ± 0.03	−0.0012 ± 0.003
MLCL	109.0 ± 0.2	36.3 ± 0.1	28.3 ± 0.1	6.54 ± 0.04	0.020 ± 0.004

Area per lipid is calculated by dividing the average bilayer area by the number of lipids per leaflet. Area per acyl chain is the area per lipid divided by four for TOCL and three for MLCL. Hydrophobic thickness is the average distance between the first carbon in the acyl chains between leaflets. Standard errors were estimated using block averaging.
