Task: Please create a description for a molecule based on its representation.
Molecule SMILES: C[C@@H](O)[C@H](NC(=O)[C@@H](N)CCCN=C(N)N)C(=O)N[C@@H](CS)C(=O)N[C@@H](CS)C(=O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a tetrapeptide composed of L-arginine, L-threonine and two L-cysteine units joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-arginine, a L-threonine and a L-cysteine.
