Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: O=C([O-])[C@@H]1C[C@@H](O)C[NH2+]1
Constraint: Answer the question with complete sentences.
Result: The molecule is an L-alpha-amino acid zwitterion arising from transfer of a proton from the carboxy to the amino group of trans-4-hydroxy-L-proline; major species at pH 7.3. It is a tautomer of a trans-4-hydroxy-L-proline.
