Question
**Part A**

**Question:**
At what pH will the following tripeptide have this structure?

**Diagram Description:**
The diagram represents the molecular structure of a tripeptide. From left to right, the structure includes:

1. An amino group (NH2) attached to a central carbon (CH), which is connected to a side chain consisting of CH2 and OH groups.
2. A peptide bond formed by the adjacent carbonyl group (C=O) and nitrogen (N-H).
3. The second amino acid residue includes a central carbon with a methyl side chain (CH2CH(CH3)2).
4. Another peptide bond with a carbonyl group.
5. The third residue contains a CH2 group linked to a carboxylate ion (C=O-O-).

**Answer Options:**
- ○ pH 1 and pH 7
- ○ there is no pH where this form exists
- ○ pH 1, pH 7, pH 12
- ○ pH 7 and pH 12
- ○ pH 7
- ○ pH 12
