Part Descriptions

LP14913-5   Porphyrins
A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, hematoporphyrin, etc. The porphyrins, in combination with iron, form the heme component in biologically significant compounds such as hemoglobin and myoglobin.

LP14913-5   Porphyrins
Porphyrins are created as byproducts of porphyrinogens. Hereditary enzyme disorders leading to the buildup of porphyrins or porphyrinogens cause porphyrias and affect the heme biosynthetic pathway. Most of these disorders are inherited as autosomal dominant disorders. Increased urine porphyrins are seen with congenital erythropoietic porphyria, acute intermittent porphyria, hereditary coproporphyria, variegate porphyria, and porphyria cutanea tarda.
