Task: Please create a text description for a molecule.
SMILES: CCCCCCCCCCCCCCCCCCCCCCC(C(=O)[O-])C(O)CCCCCCCCCCCCCCCCCC1CC1CCCCCCCCCCCCCCCCC(=O)C(C)CCCCCCCCCCCCCCCCCC
Constraint: Answer the question with full sentences.
Result: The molecule is a very long-chain fatty acid anion that is the conjugate base of keto mycolic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a mycolate, a branched-chain fatty acid anion, a very long-chain fatty acid anion and an oxo fatty acid anion. It is a conjugate base of a keto mycolic acid.
