Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces. Chemical digestion breaks large food molecules down into their chemical building blocks which can then be absorbed through the intestinal wall and into the general circulation.

Intestinal brush border enzymes and pancreatic enzymes are responsible for the majority of chemical digestion. The large intestine produces no digestive enzymes chemical digestion is completed in the small intestine before the chyme reaches the large intestine. The pH in the colon varies between 55 and 7 slightly acidic to neutral.

• reduce nutrients into smallest possible unit to be absorbed chemical digestion - specific transport proteins which control th erate of absorption and what gets absorbed - absorbs what is required - allows active transport against gradient more effective because of active transport. The digestion of proteins and carbohydrates which partially occurs in the stomach is completed in the small intestine with the aid of intestinal and pancreatic juices. Lipids arrive in the intestine largely undigested so much of the focus here is on lipid digestion which is facilitated by bile and the enzyme pancreatic lipase.
