Dietary nutrients in the digestive system
Protein
Proteins can be found in many different types of foods. They can be found in beans, meat and even eggs. The proteins contained within this food are used to build and repair body tissues. However, before these body tissues can be repaired by using the proteins, the proteins must be broken down and digested by enzymes in the digestive system. An enzyme breaks down and is in the juice of the stomach. This starts the digestion of the proteins that are contained within different food’s such as meat. Enzymes that are present in the pancreas and the lining of the intestine complete the breakdown of the large protein molecules into the smaller protein molecules. The proteins that are broken down are then absorbed into the small intestine and into the blood, it helps to build and repair cells and walls of the body. Enzymes from the pancreatic juice break down the protein molecules into amino acids. This helps in the breakdown of food. Amino acids are absorbed into the blood capillaries and transported around the body. Proteins can be digested into the liver where they are stored as fats or glycogen or converted into fatty acids. The stored proteins are used for energy:
