User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a peptide cation that is the conjugate acid of beta-alanyl-L-arginine, arising from the deprotonation of the carboxy group and protonation of both the primary amino and guanidino groups; major species at pH 7.3. It is a conjugate acid of a beta-alanyl-L-arginine.
Assistant: This is a molecule that fits your description: NC(N)=[NH+]CCC[C@H](NC(=O)CC[NH3+])C(=O)[O-]
