User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a 2-amino-4-oxopentanoic acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of (R)-2-amino-4-oxopentanoic acid; major microspecies at pH 7.3. It is a tautomer of a (R)-2-amino-4-oxopentanoic acid.
Assistant: This is a molecule that fits this description: CC(=O)C[C@@H]([NH3+])C(=O)[O-]
