Abstract
Hydrophobic spin labeling of fatty acyl residues at 5-, 12- or 16-posi tions of phosphatidylcholine liposomes reveals the involvement of surf ace moieties of bilayer (up to fifth carbon atom of fatty acyl) into i nteraction with polyadenylic acid: polyuridilic acid duplex and magnes ium ions. P-31 NMR spectra of this system demonstrate participation of nucleotide phosphoryl groups and metal cations in ternary complexatio n.
