qhov twg bilirubin conjugation tshwm sim?
sib cog lus. Hauv lub siab, bilirubin yog conjugated nrog glucuronic acid los ntawm enzyme glucuronyltransferase, ua ntej rau bilirubin glucuronide thiab tom qab ntawd mus rau bilirubin diglucuronide, ua rau nws soluble hauv dej: conjugated version yog lub ntsiab ntawm bilirubin. tam sim no nyob rau hauv "direct" bilirubin feem.
