Abstract

The effect of various monovalent cations on the state of the surface of the liposomes has been studied by the e.s.r. method using hydrophobic spin probes. Addition of monovalent cations to the liposome incubation medium changed the partition coefficients of the probes I_{1, 14}. and CAT₁₂ between liposomes and medium. With rise in the concentration of the cations their action grew, the effectiveness of the cation diminishing in the sequence NH⁺₄ > Li⁺ > Na⁺ > K⁺ ≥ Rb⁺ ≥ Cs⁺.
