Task: Please create a text description for a molecule.
SMILES: C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5C=C)[C@](C)(O)[C@@]41CCC(=O)O1)c(CCC(=O)O)c3C.[Fe+2]
Constraint: Answer the question with full sentences.
Result: The molecule is a metallochlorin that is heme d in which the hydroxy group and the carboxy group of the 6-carboxyethyl substituent have undergone intramolecular condensation to afford the corresponding gamma-spirolactone. It is a ferroheme, a gamma-lactone, an azaspiro compound, an oxaspiro compound, a tertiary alcohol, a monocarboxylic acid and a metallochlorin. It derives from a heme d cis-diol. It is a conjugate acid of a cis-heme d hydroxychlorin gamma-spirolactone(1-).
