Description (简体中文)
Biochem/physiol Actions
It appears to function as an antioxidant and efficient peroxyl radical scavenger, protecting membrane lipids from oxidation by these radicals. At nanomolar concentrations it has been shown to protect neurons from oxidative damage.
Well over 99% of total bilirubin is transported as a conjugate with albumin. Abnormally high levels of bilirubin can cause severe neurological damage, but mildly elevated levels are linked to protection from oxidative stress.
Protect from light.
Other Notes
A major component of hemoglobin decomposition. The principal pigment of bile, and the yellow color in jaundice.
