User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a hexaric acid anion obtained by deprotonation of the two carboxy groups of 3-deoxy-D-threo-hex-2-ulosaric acid; major species at pH 7.3. It is a conjugate base of a 3-deoxy-D-threo-hex-2-ulosaric acid.
Assistant: This is a molecule that fits this description: O=C([O-])C(=O)C[C@@H](O)[C@H](O)C(=O)[O-]
