Question : How is digested fat absorbed in the alimentary canal? |
| Answer» Solution :In the intestinal lumen, long chain fatty acids, monoglycerides, CHOLESTEROL and bile salts aggregate to form mixed MICELLES which are water soluble. These are taken by intestinal mucosal cells by pinocytosis. Inside the mucosal cells, fatty acids and monoglycerides react to form triglycerides which are covered by a coat of `beta`-lipoproteins to form chylomicrons which are released in lymph capillaries CALLED LACTEALS. | |
