User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 2-hydroxydicarboxylic acid that is succinic acid in which one of the hydrogens attached to a carbon is replaced by a hydroxy group. It has a role as a food acidity regulator and a fundamental metabolite. It is a 2-hydroxydicarboxylic acid and a C4-dicarboxylic acid. It derives from a succinic acid. It is a conjugate acid of a malate(2-) and a malate.
Assistant: This is a molecule that fits your description: O=C(O)CC(O)C(=O)O
