Task: Please create a text description for a molecule.
Molecule SMILES: O=CCCCC/C=C\C/C=C\C/C=C\C/C=C\CCCC(=O)[O-]
Constraint: Answer the question with full sentences.
Result: The molecule is a polyunsaturated fatty acid anion that is the conjugate base of 20-oxoarachidonic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is an omega-oxo fatty acid anion, a polyunsaturated fatty acid anion and a long-chain fatty acid anion. It derives from an arachidonate. It is a conjugate base of a 20-oxoarachidonic acid.
