Task: Please create a text description for a molecule.
Molecule SMILES: CC(=O)C12N/C(=C\C3=NC(=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 full sentences.
Result: The molecule is the intermediate in the biosynthesis of vitamin B12 from uroporphyrinogen III in which five methyl groups have been introduced into the tetrapyrrole framework, together with ring contraction. It is a conjugate acid of a precorrin-5(8-) and a precorrin-5(7-).
