User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is the alpha-amino-acid cation formed from carboxyspermidine by zwitterion formation between the carboxy and alpha-amino groups and protonation of the nitrogen atoms at positions 5 and 10; the major structure of carboxyspermidine at pH 7.3. It is a conjugate acid of a carboxyspermidine.
Assistant: This is a molecule that fits this description: [NH3+]CCCC[NH2+]CC[C@H]([NH3+])C(=O)[O-]
