  • Title: [Proteolipids of brain myelin and synaptosomes in the frog and hen].
    Author: Denisova NA, Zabelinskiĭ SA.
    Journal: Zh Evol Biokhim Fiziol; 1986; 22(4):394-9. PubMed ID: 3490079.
    Abstract:
    Proteolipid complex of Folch-Lees has been obtained and purified from the myelin and synaptosomes of the brain of the frog Rana temporaria and hen Gallus domesticus. Relative content of this proteolipid and glycolipids in the myelin is almost twice higher, whereas that of phospholipids--1 1/2 times lower than in the synaptosomal membranes of the same animal. Protein content of this complex is higher for myelin than for synaptosomal membranes; opposite relation was found with respect to phospholipid content. Within this complex, lipids are presented mainly by phospholipids, especially by acid ones which amount to 30-60%. Proteolipid complexes fro the myelin and synaptosomes differ from each other by their lipid component. Myelin proteolipid complex contains mainly phosphatidylserine and phosphatid acid, whereas synaptosomal one--phosphatidylserine and diphosphatediglycerol. No significant differences were found in fatty acid composition of phospholipids from proteolipid complex from myelin and synaptosomes as compared to this composition in the initial membranes.
