User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a branched-chain saturated fatty acid anion resulting from the deprotonation of the carboxy group of (S)-2-methylbutanoic acid. The major species at pH 7.3. It is a short-chain fatty acid anion, a branched-chain saturated fatty acid anion and a 2-methyl fatty acid anion. It is a conjugate base of a (S)-2-methylbutyric acid.
Assistant: This is a molecule that fits your description: CC[C@H](C)C(=O)[O-]
