[Metabolism of (1-14C)-palmitic acid in the cat's brain].
Following injection into the cerebral ventricles of conscious cats, (1-14C) palmitic acid was rapidly taken up and incorporated into a variety of brain lipids. The peak of uptake of (1-14C) palmitic acid, about 50% of injected radioactive material, into the brain tissue was obtained within the first 24 h following its administration. Thereafter, the radioactivity slowly decreased reaching the least value by the end of the second week. The most heavily labelled lipids were the phospholipids, while the free fatty acids were appreciably labelled. Small percentage of the radioactive material was found in monoglycerides, diglycerides and triglycerides. The least incorporation was into cholesterol esters.
