Popis:	The thermotropic phase behavior of three difluorodimyristoylphosphatidylcholines, containing a difluoromethylene group in the 2-acyl chain at either the 4-, 8-, or 12-position, has been studied by differential scanning calorimetry (DSC) and by 31 P nuclear magnetic resonance (NMR) spectroscopy at temperatures at and below their normal gel to liquid crystalline transition. The fluorinated lipids have been found to behave in a manner similar to their protonated counterpart with the exception of the 4,4-difluoro isomer
