β¦ Synopsis
A method has been developed that permits the quantitative analysis of [W]acyl-acyl carrier proteins and [W] acyl CoAs from a typical reaction mixture. The method is based on (a) the initial extraction of free fatty acids and the less polar lipids into petroleum ether from aqueous isopropanol; (b) the precipitation of [Wlacyl-acyl carrier proteins in the presence of ammonium sulfate and chloroform-methanol; and (c) the final separation of acyl CoAs from the more polar lipids by selective adsorption on neutral alumina gel. All fractions can then be analyzed for the composition of complex lipids and W-labeled fatty acids by the usual methods.

The liver plays a central role in lipoprotein metabolism. In particular, very-low density lipoprotein (VLDL) is assembled in the hepatocytes and secreted into the blood circulation. The VLDL is then catabolized to low-density lipoprotein by lipoprotein lipase and hepatic triglyceride lipase. Obese s
