Urochrome comparison
Is this the same thing as urochrome? —Keenan Pepper 05:13, 11 March 2006 (UTC)
 * Both definitions sound eerily similar, I admit. This one seems more extensive, maybe urochrome's an alt name? Let's leave them separate with these discussion lines open so someone informed can inform us. Tyciol 10:38, 3 September 2006 (UTC)

Afaik urochrome is a peptide conjugation of urobilin. urobilin itself isn't responsible for the colour of urine according to a text on urinalysis I was just reading. — Preceding unsigned comment added by 101.98.150.144 (talk) 10:29, 19 September 2013 (UTC)

The article as written implies pee turns yellow on contact with air?
Colorless Urobilinogin turns into urobilin only on contact with air? This does not pass the smell test 2603:6010:4900:163:8565:2F63:B8:7D82 (talk) 08:06, 27 March 2023 (UTC)

Urine's yellow color and exposure to air: correction
I edited the article to remove the comment that suggested that urobilin oxygenation by atmospheric oxygen was responsible for the yellow color of urine. This, obviously, is absurd, given the lack of air in the urinary tract and that urine is colored when voiding--prior to any exposure to air. If anyone has objections, please voice them here.

And the smell--not due to bilirubin but rather amine compounds (e.g. ammonia, esp. when left standing)... DrKC MD (talk) 23:47, 21 February 2024 (UTC)
