Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CSCC[C@@H](NC(C)=O)C(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is a D-alpha-amino acid anion resulting from the removal of the proton from the carboxy group of N-acetyl-D-methionine. It is a conjugate base of a N-acetyl-D-methionine. It is an enantiomer of a N-acetyl-L-methionine(1-).
