Incorporation of Infused Palmitic-1-C 14 and Linoleic-1-C 14 into Plasma Lipid Fractions. ∗

Summary

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 1) persist longer in the plasma as the FFA and 2) to be incorporated preferentially into cholesterol esters and phospholipids.
