The acid phospholipids with different long alkyl head groups were prepared total synthetically by direct phosphorylation with phosphorus oxychloride as well as partial synthetically by transphosphorylation with phospholipase D.The characterization was provided by 13C-NMR-spectroscopy, elementary analytically as well as by the phase behaviour, that was determined optically and calorimetrically.The conversion temperatures decrease with increasing number of methylene groups with alkyl head groups systematically, but the conversion enthalpies increases with growing head group length.The conversion temperatures of the phospholipids with perdeuterium head groups don't correspond with their labelled analogues.
