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|
