Uroerythrin is a red pigment present in the urine, where it is part of a group of yellow, brown and red pigments generally designated as urochrome.[2]
Urinary pigments
Pigments excreted in urine are partially absorbed by
Clinical significance
From early clinical observations it is known that uroerythrin is present in every urine and increased amounts are observed in pathological states, e.g. metabolic disorders with high fever or tissue degradation.[4]
Chemical structure
The chemical structure of most of urochromes is still unknown, since they are very labile pigments that are easily decomposed in the light. In particular uroerythrin, remains unresolved until 1975 with previous papers that describes it like a peptidic compound.[5][6][7] In 1975 its structure was described based on mass spectrometry, infrared spectroscopy and nuclear magnetic resonance.[2]
