Synthesis of Fatty Acids by Rat Intestine in vitro . ∗

Abstract

Summary

Slices of rat intestine have been shown to incorporate acetate-1-C¹⁴ into fatty acids. Stearic acid was the predominant fatty acid which was synthesized and it was found primarily in the phospholipid fraction. Addition of carnitine in vitro stimulated fatty acid synthesis but did not alter the distribution of C¹⁴ in the fatty acids or lipid classes. The intestine was also able to convert C¹⁴-palmitate into labeled stearate.
