User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a dipeptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of Ile-Gly. Major species at pH 7.3. It has a role as a metabolite. It is a tautomer of an Ile-Gly.
Assistant: This is a molecule that fits this description: CC[C@H](C)[C@H]([NH3+])C(=O)NCC(=O)[O-]
