Question

The fats absorbed from the gut are transported to the blood in the form of

• A. Micelles
• B. Chylomicrons
• C. Chemomicrons
• D. Liposomes

Answer 1

The correct option is B Chylomicrons

The products of lipid digestion enter the body by a different process and a different route. These products namely, long chain fatty acids, monoglycerides and diglycerides are insoluble in water and cannot be directly absorbed from intestinal contents. They combine with the bile salts and phospholipids to form small spherical water-soluble molecular aggregates called micelles. From the micelles, fatty acids, glycerides and fat-soluble vitamins are actively absorbed into the intestinal cells. In these cells, the bile salts are freed and fatty acids, glycerol, monoglycerides and diglycerides are resynthesized into fats. The fats are then mixed with cholesterol and coated with special proteins forming small globules called chylomicrons The latter are transported by exocytosis out of the epithelial cells into a lacteal.

Thus, the correct answer is option B.
