11. Once absorbed by the enterocyte, cholesterol is reassembled into intestinal lipoproteins called chylomicrons . 12. These chylomicrons then pass into the lacteals, forming a milky substance known as chyle. 13. At this point, the fats are in the bloodstream in the form of chylomicrons . 14. TGs, as major components of VLDL and chylomicrons , play an important role in metabolism. 15. Since there is no or little assimilation of chylomicrons , their levels in plasma remains low. 16. This interaction causes the endocytosis of the chylomicron remnants, which are subsequently hydrolyzed within lysosomes. 17. Apolipoprotein B is the primary apolipoprotein of chylomicrons , fats carried within into the cells ). 18. The triacylglycerol is then combined with phospholipids, cholesterol ester, and apolipoprotein B48 to form chylomicrons . 19. Most of the cholesterol absorbed during intestinal transport undergoes ACAT-mediated esterification before incorporation in chylomicrons . 20. Various tissues can capture the chylomicrons , releasing the triglycerides to be used as a source of energy.
