Task: Please create a molecule SMILES based on the text description.
Description: 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.
Result: O=C([O-])C(=O)C[C@@H](O)[C@H](O)C(=O)[O-]
