fluorescent lecithin probes containing cis- or trans-parinaric acid ( pna ) at the 2-position cis-parinaroylphosphatidylcholine ( cis-pnpc ) and trans-parinaroyl phosphatidylcholine ( trans-pnpc ) ) showed similar behavior to that of the free cis- or trans-parinaric acids ( cis-pna or trans-pna ) in bilayer vesicles of synthetic saturated lecithins .
