You'll need that piece of bread just in front of you. So, are you ready to use your enzymes for the sake of science?Ĭel: Well, I'm always looking for new skills for my CV. Miss Armit: And carbohydrates, like bread, are broken down by carbohydrase enzymes. Miss Armit: Yes, so as we just saw, lipids such as fats and oils are broken down by lipase enzymes.Ĭel: Proteins, like meat or pulses, are broken down by protease enzymes. Miss Armit: That, Cel, is the wonder of the human body.Ĭel: And it's pretty helpful that each of the three main types of enzymes in the digestive system are named after the food group they help break down. Helped by bile from the liver, lipase enzymes break down the lipids into fatty acids and glycerol, so they can be stored.Ĭel: Whoa! OK, so our bodies are constantly working without us even knowing about it. Stomach acid helps protease enzymes to destroy harmful microorganisms that may be present in the food.įats and oils, or lipids, provide insulation and an energy store for our bodies. Then protease enzymes in your stomach break down the proteins that will build new cells and repair damaged tissue. When you chew carbohydrate-rich foods, carbohydrase enzymes, such as amylase in your saliva, break down starch into sugar to give us the energy we need. They are called carbohydrase enzymes, protease enzymes and lipase enzymes.Ĭarbohydrates found in starchy and sugary foods are an important source of energy in a healthy diet. Three key types of enzymes in different parts of our digestive system help break down the food to provide the energy our body needs to grow and repair. ![]() VOICEOVER: Enzymes of the digestive system.
