Biological Activity

Bilirubin is a tetrapyrrole metabolite produced during heme catabolism that acts as a physiological, chain-breaking antioxidant. It effectively scavenges peroxyl radicals and suppresses lipid peroxidation, thereby protecting cellular membranes and biomolecules from oxidative damage. By mitigating reactive oxygen species accumulation, bilirubin modulates cellular oxidative stress pathways and exerts cytoprotective effects to maintain cellular homeostasis. [1]
