"Unraveling the Mystery: Scientists Crack the Code Behind Yellow Urine"

After over 150 years of mystery, scientists have identified bilirubin as the key enzyme responsible for giving urine its yellow color. This breakthrough sheds light on the process by which red blood cells degrade into bilirubin, which is then transformed by gut microbes into urobilin, the yellow pigment in urine. The discovery has potential implications for understanding and treating conditions such as jaundice and inflammatory bowel disease, and may lead to further insights into the role of gut microbiomes in human health.
