Fatty acid transport into the brain

Technical Report ·
OSTI ID:6665733
Fifteen ..mu..c of 1-/sup 14/C palmitate was injected into three groups of rats. Group I served as control animals, group II animals were subjected to functional hepatectomy, and group III animals received the tracer by an intracarotid injection followed by decapitation fifteen seconds later. The circulating blood lipids in the control group had most of the radioactivity in the triglyceride fraction whereas in both hepatectomized and carotid injected rats the blood free fatty acid (FFA) fraction had most of the radioactivity. Under these conditions the uptake of radioactivity by the brain was about six times higher in hepatectomized animals and fourteen times higher in the intracarotid injected animals than in the control group. This indicates that FFA is a preferred form of fatty acid transport to the brain.
