Task: Please generate a SMILES based on the description.
Description: The molecule is a D-alpha-amino acid zwitterion arising from the transfer of a proton from the carboxy to the amino group of D-norleucine; major species at pH 7.3. It is a tautomer of a D-norleucine.
Result: CCCC[C@@H]([NH3+])C(=O)[O-]
