User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a peptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of Ala-Leu. It is a tautomer of an Ala-Leu.
Assistant: This is a molecule that fits this description: CC(C)C[C@H](NC(=O)[C@H](C)[NH3+])C(=O)[O-]
