A) bilirubin
B) biliverdin
C) stercobilin
D) urobilinogen
Correct Answer: D
Solution :
Stercobilin is the pigment that imparts the characteristic brown-red colour to stools. Bilirubin is reduced to urobilinogen by bacterial flora. Urobilinogen is further reduced to strecobilinogen. Oxidation of stercobilinogen in air yields stercobilin.You need to login to perform this action.
