Description

L-Urobilin belongs to the class of organic compounds known as bilirubins. These are organic compounds containing a dicarboxylic acyclic tetrapyrrole derivative. L-Urobilin is a very strong basic compound (based on its pKa). Many urine tests (urinalysis) monitor the amount of urobilin in urine, as its levels can give insight on the effectiveness of urinary tract function. Darker urine can also be due to other chemicals, such as various ingested dietary components or drugs, porphyrins in patients with porphyria, and homogentisate in patients with alkaptonuria. Some of this remains in the large intestine, and its conversion to stercobilin gives feces its brown color. When urobilinogen is exposed to air, it is oxidized to urobilin, giving urine its yellow color. Bilirubin is then excreted as bile, which is further degraded by microbes present in the large intestine to urobilinogen. It is a linear tetrapyrrole compound that, along with the related compound urobilinogen, are degradation products of the cyclic tetrapyrrole heme. Urobilin is generated from the degradation of heme, which is first degraded through biliverdin to bilirubin. Urobilin or urochrome is the chemical primarily responsible for the yellow color of urine. Obstructive jaundice reduces biliary bilirubin excretion, which is then excreted directly from the blood stream into the urine, giving a dark-colored urine but with a paradoxically low urobilin concentration, no urobilinogen, and usually with correspondingly pale faeces. A lack of water intake, for example following sleep or dehydration, reduces the water content of urine, thereby concentrating urobilin and producing a darker color of urine.
