User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 2-oxo monocarboxylic acid that is pyruvic acid in which one of the methyl hydrogens is substituted by a hydroxy group. It is an intermediate involved in the glycine and serine metabolism. It has a role as a human metabolite and an Escherichia coli metabolite. It is a 2-oxo monocarboxylic acid, a 3-hydroxy monocarboxylic acid and a primary alpha-hydroxy ketone. It derives from a pyruvic acid. It is a conjugate acid of a 3-hydroxypyruvate.
Assistant: This is a molecule that fits this description: O=C(O)C(=O)CO
