![]() If we didn't have enzymes, the molecules of food would be too big to pass into our bloodstream and travel around the body to where they need to be.Ĭel: So, carbohydrase and protease and lipase, the three main types of digestive enzymes, are vital to make our bodies work?Ĭel: Awesome. We eat food to get the energy and nutrients that our bodies need. But, Miss, why does everything we (eat) need to be broken down? I mean, what's the point? And as we learned before, the carbohydrase enzyme in saliva is called amylase.Ĭel: This is definitely an experiment you can try at home. Carbohydrase enzymes break carbohydrates – in this case the starch – into sugar, which is why when you chew for a long time the bread tastes sweet. Bread contains starch, which is a carbohydrate, so please get munching.Ĭel: Oh, you don't have to ask me twice. We're going to conduct an experiment to prove what carbohydrase enzymes break carbohydrates down into. 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. The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to. 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. Pepsin is a potent enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, and dairy products 12. Generic Name Pepsin DrugBank Accession Number DB13198 Background. VOICEOVER: Enzymes of the digestive system. Pepsin is a protease indicated in the treatment of digestive disorders.
