What is the role of small intestine in digestion of proteins?

Explanation

### Step-by-Step Solution:

1. **Understanding the Role of the Small Intestine**: The small intestine is a crucial organ in the digestive system where the majority of digestion and absorption occurs. It is specifically the major site for protein digestion.

2. **Enzymatic Breakdown of Proteins**: The digestion of proteins in the small intestine is facilitated by specific enzymes known as proteases. These enzymes are responsible for breaking down proteins into smaller peptides and amino acids.

3. **Source of Proteases**: The pancreas plays a significant role in protein digestion by secreting various digestive enzymes, including proteases, into the small intestine. These enzymes are initially secreted in an inactive form known as zymogens.
