The lymphatic system is responsible for transporting the majority of dietary fats from the gut into the circulation, a process that is entirely dependent on a single critical protein. Specifically, the protein chylomicrons require in order to enter the lymph is called SAR1B, which is essential for transporting these lipid-rich particles out of intestinal cells.

The human body absorbs dietary fat with remarkable efficiency, with over 95% of ingested triglycerides being processed and absorbed. This absorption relies on the intricate formation and secretion of chylomicrons, the specialized lipoproteins responsible for transporting dietary lipids from the intestines to the rest of the body.
