  • Title: Sensitivity of 5'-nucleotidase and phospholipase A2 towards liver plasma membranes modifications.
    Author: Momchilova A, Petkova D, Mechev I, Dimitrov G, Koumanov K.
    Journal: Int J Biochem; 1985; 17(7):787-92. PubMed ID: 2996956.
    Abstract:
    The changes in the phospholipid and fatty acid composition of liver plasma membranes isolated from rats, fed two different diets, containing either saturated or unsaturated fatty acids, were investigated. We established that dietary treatment can considerably modify the fatty acid as well as the phospholipid composition of liver plasma membranes. Lipid transfer proteins were used for enrichment of liver plasma membranes with sphingomyelin, dioleoylphosphatidylcholine, dipalmitoylphosphatidylcholine, and phosphatidylinositol. A marked sphingomyelin and membrane fluidity dependence of the membrane-bound 5'-nucleotidase and phospholipase A2 was observed.
