Key Digestive Enzymes: A Comprehensive Overview

There are more than three digestive enzymes, but some of the most important ones include:

- Proteases, which break down proteins into smaller peptides and amino acids. These include enzymes such as pepsin, trypsin, and chymotrypsin.

- Lipases, which break down fats and oils into smaller fatty acids and glycerol. These include enzymes such as pancreatic lipase and bile salt-stimulated lipase.

- Amylases, which break down carbohydrates into smaller sugars, such as glucose. These include enzymes such as salivary amylase and pancreatic amylase.

- Nucleases, which break down nucleic acids into smaller nucleotides and nucleosides. These include enzymes such as deoxyribonuclease (DNase) and ribonuclease (RNase).

- Cellulases, which break down cellulose, a type of carbohydrate found in plant cell walls. These enzymes are produced by some bacteria and fungi.

- Lactase, which breaks down the milk sugar lactose into the simple sugars glucose and galactose.
