Task: Please create a description for a molecule based on its representation.
SMILES: N[C@@H](CC[Se]C[C@H](N)C(=O)O)C(=O)O
Constraint: Answer the question with complete sentences.
Result: 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.
