Abstract
Summary
Fasting lymph and lymph following feeding of a mixture containing cholesterol and oleic acid were analyzed for their CEFA composition by gas-liquid chromatography. The major fatty acids of fasting lymph were palmitic, linoleic and oleic acids, with polyunsaturated fatty acids comprising 36% of total CEFA. After feeding oleic acid only 42.3% of total CEFA was present as oleic acid. Our results support the concept that CEFA composition is not determined solely by dietary fatty acid, but by the composition of the fatty acid pool in the mucosa from which fatty acids are drawn for esterification of cholesterol.
