| Popis: | The cation permeability and size of sonicated phospholipid vesicles were found to be relatively resistant to osmotic strain. The density of 4% phosphatidic acid-96% phosphatidylcholine vesicles was found to be almost unaffected by the presence of choleserol up to a molar ratio of 1:1, the mean value was 1.014. A possible water structure effect was detected in the difference in sign between the dependence of diffusion coefficient on lipid concentration in 0.16 M KCl and 0.16 M NaCl. |
