User: I want to come up with a molecule SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, the molecule can be described by:
The molecule is an optically active form of selenocystathionine in which both amino acid residues have L-configuration. It is a tautomer of a L-selenocystathionine zwitterion.
Assistant: Got it, this SMILES fits this description: N[C@@H](CC[Se]C[C@H](N)C(=O)O)C(=O)O
