Incorporation of Infused Palmitic-1-C14 and Linoleic-1-C14 into Plasma Lipid Fractions.

Abstract
Palmitic-1-C14 and linoleic-1-C14 acids were infused into fasted dogs, and fractionation of the serum lipids carried out at time intervals up to 72 hours. Although many similarities were found in the metabolism of these 2 fatty acids, it was observed that linoleic-C14 acid appeared to persist longer in the plasma as the free fatty acid and to be incorporated preferentially into cholesterol esters and phospholipids.
