There are generally three types of enzymes.

Amylase (Carbohydrate) enzymes, Pepsin (Protease) enzymes and lipase enzymes.

Amylases break down starch in carbohydrates into sugars that can be used by the body. These enzymes are most commonly found in the salivary glands, small intestine, pancrease and stomach.

Pepsin breaks down proteins into amino acids. These enzymes are found in the small intestinf, the pancreas and the stomach.

Finally lipases, these enzymes break down fats and oils into fatty acids and a glycerol molecule. These enzymes are founs in the small intestine and the pancreas.
