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