Task: Please create a description for a molecule based on its representation.
SMILES: CSCC[C@H](NC(=O)[C@H](CCSC)NC(=O)[C@H](CCSC)NC(=O)[C@@H](N)CCCCN)C(=O)O
Constraint: Answer the question with full sentences.
Result: The molecule is a tetrapeptide composed of L-lysine and three L-methionine units joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-lysine and a L-methionine.
