A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids, di- and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglyceride.
Lacteals absorb digested fats. In the small intestine most food is digested. The digestive system's organs work to make the food you eat soluble, so your body can absorb the energy (glucose).
