Task: Please create a text description for a molecule.
Molecule SMILES: CO[C@H]1/C=C/O[C@@]2(C)Oc3c(C)c([O-])c4c(O)c(cc(OCC(=O)[O-])c4c3C2=O)NC(=O)/C(C)=C\C=C\[C@H](C)[C@H](O)[C@@H](C)[C@@H](O)[C@@H](C)[C@H](OC(C)=O)[C@@H]1C
Constraint: Answer the question with full sentences.
Result: The molecule is a hydroxy monocarboxylic acid anion arising from deprotonation of the carboxy and 5-carboxy groups of rifamycin B; major species at pH 7.3. It is a conjugate base of a rifamycin B.
