Fully hydrated samples of dipalmitoylphosphatidylcholine (DPPC, 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine), the lipid used in the first studies with synchrotron radition show a series of three well-defined transitions in the temperature range between 15 and 45 °C which are termed sub- (around 17 °C), pre- (around 33 °Q and main transition (41,4 °C) for a detailed investigation of the static X-ray diffraction behaviour of this system, see Refs. The underlying structures are schematically depicted in Figure 6a. The transition parameters, temperature and enthalpies, are constant only above a limiting value of full hydration (25 moles H O per mol DPPC, i.e. approximately 38 weight- % H O), and are sensitive also to the ionic environment.
