Protein digestion begins in the stomach, where enzymes like pepsin break down proteins into smaller peptides. These peptides then travel to the small intestine, where they’re further broken down ...

This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. Pepsin has an optimum of pH 2.5 and a working range of between pH 1-4.

Protease (Pepsin, Trypsin, Chymotrypsin) – Responsible for breaking down proteins into amino acids, aiding muscle growth and tissue repair. Lipase – Digests fats into glycerol and fatty acids ...

Along the way, food is broken down, sorted ... digestion using specialized proteins called enzymes. Secreted at various points along the digestive tract, enzymes break down large molecules ...
