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 valeric acid carrying oxo- and methyl substituents at C-2 and C-3, respectively. An alpha-keto acid analogue and metabolite of isoleucine in man, animals and bacteria. Used as a clinical marker for maple syrup urine disease (MSUD). It has a role as a human metabolite. It derives from a valeric acid. It is a conjugate acid of a 3-methyl-2-oxovalerate.
Assistant: This is a molecule that fits this description: CCC(C)C(=O)C(=O)O
