| Abstract: | The fatty acid composition of phospholipids of mitochondria and microsomes from rat liver and hepatoma 27 was investigated. Basing on the fatty acid and phospholipid composition the unsaturation of the lipid bilayer of the intracellular membranes was calculated. The unsaturation of the phospholipids of the hepatoma mitochondria and microsomes was found to be much lower than that of the corresponding rat liver membranes. The lipid bilayer of the rat liver and hepatoma plasma membranes was shown to be more saturated than that of the intracellular membranes. |
