The food molecules that are absorbed from the small intestine lumen into the lacteal, the lymphatic capillary located within the villus would be the lipids. Most of the dietary lipids are neutral fat or the so-called triglyceride. These are composed of a glycerol backbone wherein each carbon is linked to a fatty acid. In the small intestine, the villi, microvilli and plicae circulares functions to increase the surface ares that is available for the absorption of the nutrients. Each of the villus consists of a network of capillaries and lymphatic vessels which are called the lacteals which is responsible for the absorption of lipids.
