Task: Please create a description for a molecule based on its representation.
Molecule SMILES: CC(C)C[C@H](N)C(=O)N[C@@H](CO)C(=O)N[C@@H](CO)C(=O)N[C@@H](Cc1ccc(O)cc1)C(=O)O
Constraint: Answer the question with full sentences.
Result: The molecule is a tetrapeptide composed of L-leucine, two L-serine units and L-tyrosine joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-leucine, a L-serine and a L-tyrosine.
