User: I want to generate a molecule SMILES.
Assistant: This sounds very exciting. Should it be a special molecule?
User: Yes, the molecule can be described by:
The molecule is a peptide cation obtained by deprotonation of the carboxy terminus and protonation of the side-chain guanidino group and the amino terminus of Phe-Arg; major species at pH 7.3. It is a conjugate acid of a Phe-Arg.
Assistant: Got it, this SMILES fits your description: NC(N)=[NH+]CCC[C@H](NC(=O)[C@@H]([NH3+])Cc1ccccc1)C(=O)[O-]
