Effect of free fatty acids and cholesterol in vitro on liver plasma membrane-bound enzymes.

S Leoni, P Luly, M T Mangiantini, S Spagnuolo.   

Abstract

The effect of cholesterol and fatty acid treatment in vitro was tested on rat liver plasma membrane-bound enzymes and lipid fluidity. The observed alterations of membrane fluidity affect both (Na+-K+)-ATPase and Mg2+-ATPase activities but not 5'-nucleotidase; basal adenylate cyclase as well as its hormonal sensitivity were differentially affected by changes of membrane microenvironment.
