Which yellow pigment, made from the breakdown of heme, gives urine its normal colour?

1. Urine colour comes mostly from the breakdown products of red blood cell destruction. 2. The liver converts heme into water-soluble forms excreted into bile and indirectly into urine. 3. That yellow pigment is urochrome; the other pigments listed colour skin, plants, or bile instead. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 25 "The Urinary System", section Urethra_
