A substance that helps in the chemical digestion of food is typically referred to as an enzyme. Enzymes are biological catalysts that speed up the chemical reactions involved in digestion, breaking down complex food molecules into simpler forms that the body can absorb. For example:
- Amylase helps digest carbohydrates.
- Protease breaks down proteins.
- Lipase aids in the digestion of fats.
These enzymes are produced by various organs in the digestive system, including the salivary glands, stomach, pancreas, and small intestine. If you have a specific aspect of digestion or a different type of substance in mind, feel free to clarify!
