Aminopeptidase, a digestive enzyme produces

Options

A. Dipeptides
B. Smaller peptides
C. Peptones
D. Amino group

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Aminopeptidase:**
- Aminopeptidase is a type of digestive enzyme that belongs to the class of enzymes known as peptidases. These enzymes are responsible for breaking down proteins into smaller peptides and amino acids.

2. **Types of Peptidases:**
- Peptidases can be categorized into two main types:
- **Endopeptidases:** These enzymes cleave peptide bonds at internal locations within the protein chain, breaking it down into smaller fragments.
- **Exopeptidases:** These enzymes cleave peptide bonds at the ends of the protein chain. Aminopeptidase is classified as an exopeptidase.

3. **Function of Aminopeptidase:**
- As an exopeptidase, aminopeptidase specifically removes amino acids from the amino (N-terminal) end of a peptide chain. This process results in the production of smaller peptides.

4. **Identifying the Correct Answer:**
- Given the options:
- Dipeptides
- Smaller peptides
- Peptones
- Amino group
- The correct answer is **smaller peptides** because aminopeptidase breaks down larger peptides into smaller peptide fragments.

5. **Conclusion:**
- Therefore, the function of aminopeptidase is to produce smaller peptides from larger peptide chains.

**Final Answer:**
Aminopeptidase, a digestive enzyme, produces **smaller peptides**.
