Explanation:
How enzymes work in your digestive system
Amylase is produced in the salivary glands, pancreas, and small intestine. One type of amylase, called ptyalin, is made in the salivary glands and starts to act on starches while food is still in your mouth. It remains active even after you swallow.
Pancreatic amylase is made in the pancreas and delivered to the small intestine. Here it continues to break down starch molecules to sugars, which are ultimately digested into glucose by other enzymes. This is then absorbed into the body’s blood circulation through the wall of the small intestine.
Protease is produced in the stomach, pancreas, and small intestine. Most of the chemical reactions occur in the stomach and small intestine. In the stomach, pepsin is the main digestive enzyme attacking proteins. Several other pancreatic enzymes go to work when protein molecules reach the small intestine.
Lipase is produced in the pancreas and small intestine. A type of lipase is also found in breast milk to help a baby more easily digest fat molecules when nursing. Lipids play many roles, including long-term energy storage and supporting cellular health.
