User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a long-chain fatty acid anion resulting from the deprotonation of the carboxy group of henicosanoic acid. Major species at pH 7.3. It is a straight-chain saturated fatty acid anion, a long-chain fatty acid anion and a fatty acid anion 21:0. It is a conjugate base of a henicosanoic acid.
