The chemical reactions and pathways involving corrin, C19H22N4, the fundamental heterocyclic skeleton of the corrinoids. It consists of four reduced pyrrole rings joined into a macrocyclic ring. Corrin is the core of the vitamin B12 molecule. The chemical reactions and pathways resulting in the breakdown of heterocyclic compounds, those with a cyclic molecular structure and at least two different atoms in the ring (or rings). The chemical reactions and pathways resulting in the breakdown of organic and inorganic nitrogenous compounds. The chemical reactions and pathways resulting in the breakdown of substances, carried out by individual cells. The chemical reactions and pathways involving 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 a cofactor, a substance that is required for the activity of an enzyme or other protein. Cofactors may be inorganic, such as the metal atoms zinc, iron, and copper in certain forms, or organic, in which case they are referred to as coenzymes. Cofactors may either be bound tightly to active sites or bind loosely with the substrate. 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 resulting in the breakdown of corrin, C19H22N4, the fundamental heterocyclic skeleton of the corrinoids. It consists of four reduced pyrrole rings joined into a macrocyclic ring. Corrin is the core of the vitamin B12 molecule. 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.
