Abstract
The relation between carnitine palmitoyltransferase (CPT) activity and 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity was investigated. Rats were treated with aminocarnitine or 1-carnitine overnight. In rats, in which CPT activity was inhibited by aminocarnitine, plasma and hepatic triacylglycerol contents were increased 5- to 6-fold. The plasma cholesterol concentration was unchanged, while the hepatic cholesterol content was lowered (−16%). Hepatic cholesterol synthesis, determined by following the incorporation of 14C-acetate and 3H2O into digitonin-precipitable sterols, in liver slices was increased 5- to 7-fold. HMG-CoA reductase activity in liver microsomes was increased to the same extent.
