User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an L-alpha-amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of S-allylcysteine. Major species at pH 7.3. It has a role as a metabolite. It is a tautomer of a S-allylcysteine.
Assistant: This is a molecule that fits this description: C=CCSC[C@H]([NH3+])C(=O)[O-]
