"Unraveling the 150-Year Mystery of Yellow Urine: Scientists' Breakthrough Discovery"
A recent study published in Nature Microbiology has identified bilirubin as the reason behind the yellow color of healthy urine, solving a 150-year mystery. The study explains that bilirubin, a byproduct of old red blood cells broken down through bodily processes, mixes with other waste products in the liver to create bile. Gut microbes then convert bilirubin into a colorless byproduct called urobilinogen, which eventually degrades into urobilin, responsible for the yellow color of urine.
