Task: Please generate a SMILES based on the description below.
Description: The molecule is a metalloprotoporphyrin in which the four pyrrole nitrogens of the protoporphyrin moiety are coordinated to iron. It is the most abundant of the heme compounds. It is a heme and a metalloprotoporphyrin.
Result: C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5CCC(=O)O)C(CCC(=O)O)=C4C)c(C)c3C=C.[Fe+2]
