Digestion enzymes are classified by their substrates: proteases and peptidases split proteins into amino acids, lipases split fat into fatty acids, carbohydrases split carbohydrates such as starch into sugars, and nucleases split nucleic acids into nucleotides.
In the human digestive system, the main sites of digestion are the oral cavity, the stomach, the duodenum, and the jejunum and digestive enzymes are secreted by different glands: the salivary glands, the glands in the stomach, the pancreas, and the glands in the small intestines.
Summary of the actions of digestive enzymes:
Enzymes are also in your mouth, helping to break down food, as well as the teeth are.
Five types of enzymes degrade disaccharides into monosaccharides:
The small intestine receives lipase, trypsin and amylase from the pancreas. They are transported from the pancreas to the duodenum through the pancreatic duct. Protein, fats and starch are broken down into smaller molecules. However, they are not fully broken down yet. This causes the enzymes of the small intestine to act upon them. These enzymes include peptidase, which breaks down peptides into amino acids and the enzyme maltase acts upon maltose which produces glucose. These molecules are absorbed by the villi in the small intestine and according to the molecule they are either absorbed by the lacteal or blood capillaries.
