Diacylglycerol (DAG) is recognized as one of the most important lipids for biological functions of cell membranes. In order to understand the functions of DAG, it is indispensable to study the effect of DAG on phosphatidylcholine (PC), which is a main lipid component of biomembranes. Here we report neutron-scattering data of sonicated PC/DAG vesicles and X-ray-diffraction data of oriented PC/DAG multilamellar systems. These data imply that addition of DAG induces a change in the tilt angle of lipid molecules and that, as a result, an increase of the membrane thickness is induced.
