Estimation of the di-C14:0-PC bilayer thickness at 313 K deduced from order parameters

Sample	Bilayer thickness* 2 × DC† (Å)
di-C14:0-PC	25.0 (25.6‡ and 24.0§)
+ 4% TFE	23.4
+ 8% TFE	21.2
WALP23	26.4
+ 4% TFE	23.2
+ 8% TFE	21.6
KALP23	25.2
+ 8% TFE	21.0

See Petrache, Dodd, and Brown (33).

^*The peptide/lipid molar ratio of samples containing peptides was 1:30. The estimated precision of the results is ± 0.1 Å, based on a standard error of 0.2 kHz in ²H NMR measurements from duplicate samples.

^†D_C represents the distance in Å of the carbonyl atom to the center of the bilayer (31–33).

^‡Data at 30°C (33).

^§Data at 50°C (33).
