The stomach secretes the enzyme pepsin to aid digestion. Pepsin mainly acts on which nutrient?
Proteins
Pepsin is a protein-digesting (proteolytic) enzyme secreted by the gastric glands of the stomach in an inactive form called pepsinogen.
The acidic environment created by hydrochloric acid in the stomach activates pepsinogen into pepsin, which then breaks down proteins into smaller peptides.
Carbohydrate digestion is handled mainly by amylase, and fat digestion by lipase, so pepsin does not act on those nutrients.
Hence, pepsin mainly acts on proteins.
