User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a zwitterion resulting from the transfer of a proton from the phosphonic acid group to the amino group of (3-aminopropyl)phosphonic acid; the major species at pH 7.3. It derives from a phosphonate(2-). It is a tautomer of a (3-aminopropyl)phosphonic acid.
Assistant: This is a molecule that fits this description: [NH3+]CCCP(=O)([O-])O
