User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is an L-alpha-amino acid that is L-valine in which all five carbons are (13)C isotopes while the nitrogen is the (15)N isotope. It is a L-alpha-amino acid, a valine, a (13)C-modified compound and a (15)N-modified compound.
Assistant: This is a molecule that fits your description: [13CH3][13CH]([13CH3])[13C@H]([15NH2])[13C](=O)O
