User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a tetrapeptide composed of L-aspartic acid and three L-valine units joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-aspartic acid and a L-valine.
Assistant: This is a molecule that fits your description: CC(C)[C@H](NC(=O)[C@@H](NC(=O)[C@@H](NC(=O)[C@@H](N)CC(=O)O)C(C)C)C(C)C)C(=O)O
