User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an L-alpha-amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of L-isoleucine; major species at pH 7.3. It is a tautomer of a L-isoleucine.
Assistant: This is a molecule that fits your description: CC[C@H](C)[C@H]([NH3+])C(=O)[O-]
