Are proteins used for digestion of food molecules?

Yes, proteins play a crucial role in the digestion of food molecules. Enzymes, which are specialized proteins, break down macromolecules like carbohydrates, fats, and proteins into smaller, absorbable units. For example, pepsin digests proteins in the stomach, while amylase and lipase target carbohydrates and fats, respectively. This enzymatic process is essential for nutrient absorption in the body.
