What are digestive enzymes and what do they do?
Digestive enzymes are biological catalysts that facilitate chemical reactions that break down complex food particles. Specifically, digestive enzymes catalyze hydrolysis reactions that break chemical bonds by the addition of water. As a result, nutrients such as starch and protein are broken down into smaller components so that they can be absorbed by the body.
