Overview. When you take in food, it's the job of your digestive tract to break that food down into smaller pieces through mechanical digestion, and then break larger molecules into smaller ones through chemical digestion.
The primary digestive enzymes are proteases (to digest proteins), amylases (to digest carbohydrates), and lipases (to digest fats). These enzymes function as a biological catalyst to help break down food.Raw foods also provide enzymes that naturally break down food for proper absorption.aliva is rich in amylase, while gastric juice contains protease. The pancreas secretes digestive juices containing high concentrations of amylase and protease, as well as a smaller concentration of lipase.
