Task: Please create a description for a molecule.
SMILES: O=C(O)C(=O)/C=C1\CC[C@@H](O)[C@@H]2O[C@H]12
Constraint: Answer the question with complete sentences.
Result: The molecule is a 2-oxo monocarboxylic acid that is pyruvic acid in which two of the methyl hydrogens are replaced by a 5-hydroxy-7-oxabicyclo[4.1.0]heptan-2-ylidene group (the 1R,5R,6S stereoisomer). It has a role as a bacterial metabolite. It is a 2-oxo monocarboxylic acid, a secondary alcohol, an epoxide, an enone and an oxabicycloalkane. It derives from a pyruvic acid. It is a conjugate acid of a (3E)-3-[(1R,5R,6S)-5-hydroxy-7-oxabicyclo[4.1.0]heptan-2-ylidene]pyruvate.
