User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a 4-hydroxy-2-oxoheptanedioate obtained by deprotonation of both carboxy groups of (S)-4-hydroxy-2-oxoheptanedioic acid; major species at pH 7.3. It is a conjugate base of a (S)-4-hydroxy-2-oxoheptanedioic acid.
Assistant: This is a molecule that fits your description: O=C([O-])CC[C@H](O)CC(=O)C(=O)[O-]
