    Abstract:
    1. Composition of phospholipids extracted from different organelles of European sea bass liver was determined and compared with that of phospholipids extracted from the same organelles of rat liver. 2. Spermine binding to the vesicles prepared from microsomal and mitochondrial phospholipids and their aggregation was studied: these parameters indicate that only the presence of acidic phospholipids and not their unsaturation was essential for polyamine action. 3. No correlation exists between polyunsaturated fatty acid and spermine inhibition of lipid peroxidation. In fact microsomal phospholipids, which have a low content of acidic phospholipids, and a prevalent presence of phosphatidylinositol, are not protected by spermine. 4. Mitochondrial phospholipids, which have high content of cardiolipin, elicit the capability of spermine to inhibit lipid peroxidation.
