Task: Please create a description for a molecule based on its representation.
SMILES: NC(N)=[NH+]CCC[C@H](NC(=O)[C@@H]([NH3+])Cc1ccccc1)C(=O)[O-]
Constraint: Answer the question with full sentences.
Result: 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.
