[Fat resorption: current concepts and micromophology].
Recent concepts in the physiology of intestinal fat absorption are reviewed and the intraluminal formation and the role of the mixed lipid micelle, the concept of the unstirred water layer and the role of the fatty acid binding protein in the intracellular transport of long chain fatty acids are particularly emphasized. It is pointed out that only little information is available on the exact mechanism of the synthesis of intestinal lipoproteins and their export from the intestinal epithelial cells. Finally, preliminary results are presented of an electron-microscopical investigation of the intestinal mucosa of rats at different intervals after intraduodenal injection of an emulsion of lipids.
