Task: Please create a description for a molecule.
SMILES: C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5CCC(=O)[O-])C(CCC(=O)[O-])=C4C=O)c(C)c3[C@@H](O)CCCC(C)CCCC(C)CCCC(C)C.[Fe+3]
Constraint: Answer the question with full sentences.
Result: The molecule is a dicarboxylic acid anion obtained by deprotonation of the carboxy groups of ferriheme a3. Major structure at pH 7.3. It is a conjugate base of a ferriheme a3.
