Which enzyme from the pancreas assists in protein digestion?

Trypsin is the enzyme from the pancreas that plays a crucial role in protein digestion. It is secreted as an inactive precursor known as trypsinogen, which is activated in the small intestine. Once activated, trypsin breaks down proteins into smaller peptides by cleaving the peptide bonds at specific amino acid residues. This process is essential for the body to absorb amino acids and peptides from dietary proteins.

In contrast, lipase is responsible for the digestion of fats, while amylase is involved in breaking down carbohydrates. Pepsin, although it digests proteins, is secreted by the stomach and operates in a different environment compared to trypsin, which functions in the alkaline conditions of the small intestine. Understanding the roles and functions of these enzymes is pivotal for comprehending the digestive process and the specific contributions of pancreatic enzymes to nutritional absorption.
