The three stages of the chylomicron are nascent, mature, and remnant. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglycerides. The triglycerides are then combined with phospholipids, cholesteryl esters, and apolipoprotein B48 (ApoB48) to form a nascent chylomicro… WebJul 30, 2024 · The lacteals come together to form the lymphatic vessels.
