By methods C NMR spectroscopy the interaction of the pyridine with phosphatidylcholine, which is phospholipid of cell membranes, was discovered. The structure of complex was determinated by semi-empirical quantum chemistry method MNDO using multiple variation of disposition of the molecule-partners. It was shown, that interaction of pyridine heterocycle with choline group of the phosphatidylcholine molecule by means of 7i-electrons is charac¬teristic of this complex.
