Task: Please create a text description for a molecule.
Molecule SMILES: O=CCCCC(=O)[O-]
Constraint: Answer the question with full sentences.
Result: The molecule is a 5-oxo monocarboxylic acid anion that is the conjugate base of 5-oxopentanoic acid, arising from deprotonation of the carboxy group. It is a 5-oxo monocarboxylic acid anion, an aldehydic acid anion, an omega-oxo fatty acid anion and a member of oxopentanoates. It derives from a valerate. It is a conjugate base of a 5-oxopentanoic acid.
