Enzymes in digestion

In the digestive system enzymes break down large insoluble molecules (e.g. starch, proteins and fats) into small soluble molecules that can be absorbed into the blood from the small intestines.

Large Insoluble Molecule Type of Enzyme Small Soluble Product
Carbohydrate (e.g. Starch) Carbohydrase Simple Sugars (e.g. glucose)
Protein Protease (e.g. pepsin) Amino Acids
Fat/Lipids Lipase Glycerol and Fatty Acids
