Fatty acids and glycerides are absorbed into the intestinal wall and re-formed into triglycerides (three fatty acids attached like streamers to a glycerol molecule), the standard form of fats in the body. Here the body confronts the next challenge of digesting fats: because they don’t mix well with water, they tend to clump together in water-based solutions like blood. Lumpy blood would kill you, clogging up the small vessels in your brain, lungs, and other organs. The evolved solution is to pack triglycerides into spherical containers called chylomicrons.
