The structure of phosphatidylcholine-pyrazole and phosphatidyl-choline-pyridwe complexes were studied using the quantum che¬mistry and C-NMR spectroscopy methods. Four sites of the geterocyclic molecule localization in the choline group of phosphati-dylcholine (PC) were detected. The complex containing the bio¬logically active molecule located near the NCH2 fragment of PC polar group was shown to be the most stable.
