Ma. Busquets et al., MISCIBILITY OF DIPALMITOYLPHOSPHATIDYLCHOLINE, OLEIC-ACID AND CHOLESTEROL MEASURED BY DSC AND COMPRESSION ISOTHERMS OF MONOLAYERS, Thermochimica acta, 232(2), 1994, pp. 261-269
The miscibility of dipalmitoylphosphatidylcholine and oleic acid (DPPC
/OA) and of dipalmitoylphosphatidylcholine/oleic acid/cholesterol (DPP
C/OA/Chol) in mixed mono-layers was determined. According to the therm
odynamic calculations, the energy involved in the process is very low,
suggesting the lack of strong interactions. Moreover, the presence of
oleic acid or cholesterol has little influence on the transition temp
erature of DPPC.
