The chemical reactions and pathways resulting in the breakdown of heme O, a derivative of heme containing a 17-carbon hydroxyethylfarnesyl side chain at position 8 of the tetrapyrrole macrocycle. The chemical reactions and pathways resulting in the breakdown of heme a, a derivative of heme found in cytochrome aa3. The chemical reactions and pathways resulting in the breakdown of siroheme, a tetrahydroporphyrin with adjacent, reduced pyrrole rings. The chemical reactions and pathways resulting in the breakdown of substances, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism. The chemical reactions and pathways resulting in the breakdown of heme c, a derivative of heme found in cytochromes c, b4, and f. The chemical reactions and pathways resulting in the breakdown of any member of a large group of derivatives or analogs of porphyrin. Porphyrin consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. The chemical reactions and pathways leading to the breakdown of tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. The chemical reactions and pathways involving any member of a large group of derivatives or analogs of porphyrin. Porphyrins consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. The chemical reactions and pathways resulting in the breakdown of a pigment, any general or particular coloring matter in living organisms, e.g. melanin. The chemical reactions and pathways involving heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring. The chemical reactions and pathways resulting in the breakdown of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring. The chemical reactions and pathways resulting in the breakdown of a cofactor, a substance that is required for the activity of an enzyme or other protein. The chemical reactions and pathways involving pigment, any general or particular coloring matter in living organisms, e.g. melanin.
