'''Urobilin''' is a yellow linear tetrapyrrole, resulting from the breakdown of [[haem]], a cyclic tetrapyrrole. Urobilin is generated in intestines from [[urobilinogen]]. It is absorbed into blood stream and excreted in urine, giving urine its characteristic yellow color.
It is a sensitive marker for early acute hepatitis.
