It acts on cane sugar and converts them into simple sugar or glucose. This enzyme splits lactose into glucose and galactose. This galactose is again converted into glucose in the liver at time of necessity. It converts maltase into dextrin.

This enzyme activates the proteolytic enzyme of pancreatic juice. It activates trypsinogen to trypsin which helps in the digestion of protein foods. The enzyme completes the digestion of protein foods. It converts peptone polypetide and other undigested protein foods into amino acids.

In this part of small Intestine the digestion of all the three types of foods are completed. Carbohydrate foods are simplified into glucose, protein into amino acids and fat into fatty acids and glycerol.

When the process of digestion is completed, they are carried to the last part of the small intestine i. The digested food reaches this place in about four hours. Ileum constitutes the last three fifth of small intestine. It is relatively thinner than jejunum. From this place the absorption of simplified and digested food starts.

By the action of various digestive juices, saliva, gastric, juice, pancreatic juice and intestinal juice, different food materials are simplified and ready for absorption.

Proteins have been broken down to peptone by gastric juice, polypeptide by pancreatic juice and finally to Amino acids by intestinal juice. Carbohydrates have been converted into maltose by salivary juice, other disaccharides by pancreatic juice and lastly mono-saccharides of glucose or simple sugar by Intestinal juice.

Fat is simplified into fatly acids and glycerol by the action of gastric lipase and pancreatic lipase. Absorption of Digested Food: Absorption of digested food take place in the epithelial surface of the villi in the Ilium part of small intestine. The mucous membrane of the small intestine is line by a number of projections like substances known as villi.

These help in absorption by increasing the surface area. A villus contains a lacteal, blood vessels, epithelium and muscular tissue, which are connected together by lymphoid tissue. Carbohydrates in the form of glucose are directly picked up by the blood vessels from the villi.

Proteins are absorbed by the blood vessels from the villi in the form of amino acids. Fats, in the form of fatly acids and glycerol are absorbed into the lacteals. Small amount of emulsified fats from water soluble compounds with bile, that are readily absorbed.

Fat soluble vitamins get absorbed along with fats. Mineral salts and small amount of water pass into the blood vessels along with sugar and amino acids.

Amino acids, glucose and fatly acid are passed from the small intestine to the liver for oxidation and metabolic process. The excess amount of glucose is converted to glycogen and is stored in the liver for future use. After absorption, intestinal contents are slowly propelled along the Alimentary canal.
