Absorption of Unsaturated Fatty Acids

Abstract

Lipid absorption in man occurs largely from the jejunum. The principal molecular species passing across the brush-border membrane of the enterocyte are the monoacylglycerols and free fatty acids. The bile salts themselves are not absorbed in the jejunum or proximal small intestine but pass on to the ileum where they are absorbed and recirculated via the portal blood to the liver and then to the bile for re-entry into the duodenum.
