Structural properties of phosphatidylcholine in a monolayer at the air/water interface

1991

Neutron reflectivities of phosphatidylcholine monolayers in the liquid condensed (LC) phase on ultrapure H 2 O and D 2 O subphases have been measured on a Langmuir film balance. Using a dedicated liquid surface reflectometer, reflectivities down to R = 10 -6 in the momentum transfer range Q z = 0–0.4A -1 were accessed. In a new approach, by refining neutron reflectivity data from chain-perdeuterated DPPC-d 62 in combination with x-ray measurements on the same monolayer under similar conditions it is shown that the two techniques mutually complement one another. This analysis leads to a detailed conception of the interface structure. It is found that in the LC phase (which is analogous to th…

X-ray scattering studies of fatty acid films on water and on Cdcl2 solutions

1991

X-ray diffraction methods for Langmuir films on the surface of water are briefly presented, together with recent results for docosanoic acid monolayers on pure water and for eicosanoic acid monolayers on an ionic subphase.
