Urobilinogen present reacts with Ehrlich's reagent to form a red-colored compound. Color changes from light orange-pink to dark pink. The test is based on a diazotisation reaction of 4- Methoxybenzene diazoniurn salt and urinary urobilinogen in a strong acid medium. The color changes from pink to brown-red.Urobilinogen is a chromogen formed in the intestine from the breakdown of a reddish-yellow water insoluble pigment. Urobilinogen is a bile pigment that is produced by the degradation of conjugated bilirubin in the biliary tree and small intestine.robilinogen present reacts with Ehrlich's reagent to form a red-colored compound.

Metabolism [edit]. Urobilin is generated from the degradation of heme, which is first degraded through biliverdin to bilirubin. Bilirubin is then excreted as bile, which is further degraded by microbes present in the large intestine to urobilinogen.Some of this remains in the large intestine, and its conversion to stercobilin gives feces its brown color.ilirubin is then excreted as bile, which is further degraded by microbes present in the large intestine to urobilinogen.

Stercobilin is a tetrapyrrolic bile pigment and is one end-product of heme catabolism.It is the chemical responsible for the brown color of human feces and was originally isolated from feces in 1932.tercobilin (and related urobilin) can be used as a marker for biochemical identification of fecal pollution levels in rivers.

The color of urine can vary from almost colorless to black. Normal urine may show color variation ranging from pale yellow to deep amber. Urine color is typically a result of the degradation of the heme molecule into a urinary pigment called urochrome.he color of urine can vary from almost colorless to black.

The principal pigment of urine, a compound of urobilin and a peptide of unknown structure. Synonym(s): urian. /uro·chrome/ (u´ro-krōm) the end product of hemoglobin breakdown, found in the urine and responsible for its yellow color.rine-Off is manufactured by Bio-Pro Research, LLC, and has a specially designed advanced formula using a combination of naturally occurring bio-enzymes to digest the uric acid salt crystals (which produce urine's pungent aroma) as well as remove the urea (sticky substance in urine) and. (makes urine yellow).

Stercobilin results from breakdown of the heme moiety of hemoglobin found in erythrocytes. Macrophages break down senescent erythrocytes and break the heme down into biliverdin, which rapidly reduces to free bilirubin.tercobilin (and related urobilin) can be used as a marker for biochemical identification of fecal pollution levels in rivers.

Normal urine is clear and has a straw yellow color, caused by a bile pigment called urobilin. As with your stool, your urine changes color depending on what foods you eat, what medications and supplements you take, how much water you drink, how active you are, and the time of the day.ormal urine is clear and has a straw yellow color, caused by a bile pigment called urobilin.

The first urination of the day, which is usually during the morning, can produce a darker color of urine. Additionally, when a person is dehydrated, there is not enough water in the urine to mix in with the urobilin, and create a lighter color.In cases of dehydration, the urine can appear darker. Of course, urine can appear amber, brown, or red in case of blood being present in urine, which is a condition called Hematuria.hen urine is dense, the urobilin can create the appearance of an orange-red color whose intensity varies with its degree of oxidation, and sometimes causes pee to look red or bloody. It can be shown not to be blood on a dipstick test or a number of other blood tests.
