[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is an oxo monocarboxylic acid anion that is the conjugate base of 8-[(1S,2S)-3-oxo-2-{(Z)-pent-2-en-1-yl}cyclopentyl]octanoic acid resulting from the deprotonation of the carboxy group; major species at pH 7.3. It is functionally related to an octanoate.
