User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a butenedioic acid in which the C=C double bond has E geometry. It is an intermediate metabolite in the citric acid cycle. It has a role as a food acidity regulator and a fundamental metabolite. It is a conjugate acid of a fumarate(1-).
Assistant: This is a molecule that fits your description: O=C(O)/C=C/C(=O)O
