Method "X-ray diffraction of multibilayers equilibrated at 98% relative humidity"
Comments “Listed in Table 1 for 98% relative humidity, the values were hpp˜43.7±0.5Å for diC22:1 [hpp=peak-to-peak headgroup thickness], hpp˜40.7±0.6Å for C18:0/1, hpp˜36.9±0.4Å for diC18:1, hpp˜34.9±0.3Å for diC18:2, hpp˜34.3±0.6Å for diC18:3, and hpp˜34.1±0.5Å for diC13:0. (As pointed out by Petrache et al. (1998a), measurements of peak-to-peak headgroup separation must also be corrected for thermal bending undulations." Note: Above thickness range for lipid chains 13-22 carbons long. Lewis et al 1983 PMID: 6854644, measured from X-ray scattering data thickness of 1.6-3.8 nm in chains 10-24 carbons long.
