Task: Please create a description for a molecule.
Molecule SMILES: CC(=O)C12N/C(=C\C3=[NH+]C(=C(CCC(=O)[O-])[C@]3(C)CC(=O)[O-])C[C@]3(C)N=C(CC4=NC1=C(CC(=O)[O-])[C@@]4(C)CCC(=O)[O-])C(CCC(=O)[O-])=C3CC(=O)[O-])[C@@H](CCC(=O)[O-])[C@]2(C)CC(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is a precorrin carboxylic acid anion that is a heptaanionic form of precorrin-5. Major microspecies at pH 7.3 (according to Marvin v 6.2.0.). It is a conjugate base of a precorrin-5. It is a conjugate acid of a precorrin-5(8-).
