User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a D-alpha-amino acid zwitterion arising from the transfer of a proton from the carboxy to the amino group of D-leucine; major species at pH 7.3. It is a tautomer of a D-leucine.
Assistant: This is a molecule that fits your description: CC(C)C[C@@H]([NH3+])C(=O)[O-]
