[Comparison of the effect of acetone and isopropanol on lipid metabolism in rats]

Abstract

Isopropanol and acetone administered to rats in conditions leading to a similar blood acetone level differ markedly in their effects on lipid metabolism. Isopropanol administration determines a fatty liver, which is mainly related to a defect in hepatic lipoprotein synthesis. Acetone administration gives only raise to a slight increase in the liver triacylglycerol level. It does not alter the [1-14C] palmitate, [1-14C] glycerol or [U-14C] leucine incorporation into blood lipoproteins. Acetone does thus not appear to play a preminent role in the isopropanol induced fatty liver which seems to be related mainly to a direct action of the alcohol itself.
