uroporphyrin [¦yu̇r·ə′pȯr·fə·rən]

(biochemistry)

Any of several isomeric, metal-free porphyrins, occurring in small quantities in normal urine and feces; molecule has four acetic acid (‒CH₂COOH) and four propionic acid (‒CH₂CH₂COOH) groups.

Uroporphyrin

any of the pigments of the porphyrin group that are similar in structure and that occur primarily in urine and feces. In a number of pathological states (porphyria, certain types of poisoning), the content of one uroporphyrin in human urine sharply increases (to several hundred mg). Uroporphyrins have been found in the shells of pearl oysters and in planarians.
