Task: Please generate a SMILES based on the description.
Description: The molecule is zwitterionic form of D-alanyl-D-serine arising from migration of a proton from the OH of the carboxy terminus to the amino terminus. It is a tautomer of a D-alanyl-D-serine.
Result: C[C@@H]([NH3+])C(=O)N[C@H](CO)C(=O)[O-]
