Task: Please create a description for a molecule.
SMILES: O=C([O-])CCc1c2[nH]c(c1CC(=O)[O-])Cc1[nH]c(c(CC(=O)[O-])c1CCC(=O)[O-])Cc1[nH]c(c(CC(=O)[O-])c1CCC(=O)[O-])Cc1[nH]c(c(CC(=O)[O-])c1CCC(=O)[O-])C2
Constraint: Answer the question with full sentences.
Result: The molecule is the cyclic tetrapyrrole anion that is the octacarboxylate anion of uroporphyrinogen I. It is a conjugate base of a uroporphyrinogen I.
