Task: Please generate a SMILES based on the text description below.
Description: The molecule is the alpha-amino-acid cation formed from carboxynorspermidine by zwitterion formation between the carboxy and alpha-amino groups and protonation of the nitrogen atoms at positions 5 and 9; the major structure of carboxynorspermidine at pH 7.3. It is a conjugate acid of a carboxynorspermidine.
Result: [NH3+]CCC[NH2+]CC[C@H]([NH3+])C(=O)[O-]
