User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a hydroxy fatty acid anion that is the conjugate base of 2-hydroxyisobutyric acid, arising from deprotonation of the carboxy group; major species at pH 7.3. It has a role as a human xenobiotic metabolite. It derives from an isobutyrate. It is a conjugate base of a 2-hydroxyisobutyric acid.
Assistant: This is a molecule that fits your description: CC(C)(O)C(=O)[O-]
