Urochrome

As Urochrome all occurring in the urine metabolites are referred to color it. Often we group them together as Urochrome without defining exactly which materials they are made. Part of the Urochrome make intermediates of the assembly and disassembly of the red blood pigment, hemoglobin, from. These bile pigments are porphyrins as the urobilins or biliverdin.

Many other metabolic products as well as ingested food and drugs affect the Harnfarbe. They can vary considerably in healthy individuals. Besides the influence of food it is based mainly on the fluid balance: Suppose plenty of fluids to us, then the urine is relatively dilute and be his color almost water-white or pale yellow. Let's take a little liquid to us or lose a lot of fluid ( diarrhea, sweating, for example, during exercise ), then the body must conserve water and excrete very little urine. The urine is then very concentrated and dark yellow.

Differences is the Harnfarbstoff as red and yellow fraction ( urobilin or Urochromfraktion ) as well as unstained protein acids ( Histidinfraktion, including the Urorosein ).

The yellow dyes, the oxidation of Urochromogenen ( class Oxyproteinsäuren ) arise ( urochrome A and B, 95 percent of the Harnfarbwertes ) are - as a hemoglobin degradation products - for a particular disease increases, and represent the actual substrate of the diazo reaction is forming a so-called residual dye group together with urobilin and Uroerythrin the normal Harnfarbe.
