Permeability and topography of membranes
Chemistry and Physics of Lipids, 1972 In this brief review, we will report that the permeability of both artificial and natural membranes depends at least on the following lipid parameters: (1) The nature of the hydrocarbon chains of phospholipids. Because of a less compact packing of unsaturated phospholipids when compared with saturated ones, the former barrier will be more permeable ...

Lysosome membrane permeability to anions
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1998 The permeability of rat liver lysosomes to some inorganic and aliphatic organic anions was investigated, using an osmotic-protection methodology. Lysosomes were incubated at 25 degreesC in 250 mOsm solutions of potassium salts of the anions, in the presence of valinomycin, and the latency of lysosomal hexosaminidase measured at intervals.
