Question
**Question:**
The structure shown here is best described as a(n)

**Image Description:**
The image depicts a chemical structure of a molecule. The structure includes three distinct amino acid units linked together. Each amino acid unit has an amine group (NH₂) and a carboxyl group (COOH). 

**Options:**
- Zwitterion
- Dipeptide
- Tripeptide
- Tetrapeptide
- Amino acid at neutral pH

**Detailed Explanation:**

The structure shown in the image is a molecular diagram featuring three amino acid residues linked by peptide bonds. This type of linkage is typical of peptides, which are sequences of amino acids forming a chain. Specifically, each peptide bond forms between the carboxyl group of one amino acid and the amine group of the next amino acid.

Given the structure includes three amino acid units, the correct description of this molecule is a _tripeptide_, which is a peptide comprised of three amino acids connected by peptide bonds. 

**Correct Option:**
- Tripeptide
