Task: Please create a description for a molecule.
SMILES: O=C/C=C/C(C(=O)[O-])=C(/[O-])C(=O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a dicarboxylic acid dianion arising from deprotonation of both carboxy groups of 2-hydroxy-3-(3-oxoprop-1-enyl)but-2-enedioic acid; major species at pH 7.3. It is a conjugate base of a 2-hydroxy-3-(3-oxoprop-1-enyl)but-2-enedioic acid.
