Key Points
- Amylase is the first enzyme to mix with food in the human digestive tract, starting the process of carbohydrate digestion.
- It is secreted by the salivary glands in the mouth, where it begins breaking down starch into simpler sugars.
- Amylase continues to act on food in the stomach for a short period before being deactivated by stomach acid.
- This enzyme is crucial for the initial phase of digestion, making complex carbohydrates easier to process in the later stages of the digestive system.
- It plays a significant role in maintaining healthy blood sugar levels by aiding efficient carbohydrate breakdown.
Additional Information
- Pepsin is another digestive enzyme, but it is active in the stomach and primarily breaks down proteins into peptides.
- Trypsin is a pancreatic enzyme that also aids in protein digestion, but it acts in the small intestine.
- Cellulase is not produced by the human body; it breaks down cellulose, a major component of plant cell walls, and is produced by some microorganisms.
