Urinary pigments
Pigments excreted in urine are partially absorbed by urate sediments ( sedimentum latrerium ), which consists of cell debris and sedimented urinary components formed when the acidified urine is stored below room temperature. These urate sediments looks reddish or pink due to the presence of a main pigment first introduced by Simons in 1842 as uroerythrin,
Clinical significance
From early clinical observations it is known that uroerytrhin is present in every urine and increased amounts are observed in pathological states, e.g. metabolic disorders with high fever or tissue degradation.
Chemical structure
The chemical structure of most of urochromes is still unknown, since they are very labile pigments that are easily descomposed in the light. In particular uroerythrin, remains unresolved until 1975 with previous papers that describes it like a peptidic compound. In 1975 its structure was descripted in base of mass spectrometry, infrared spectroscopy and nuclear magnetic resonance.
