3,3′,4,4′,5,5′-Hexabromobiphenyl, a type of brominated flame retardant, plays a role in the manufacturing of polymers and textiles. Studies have revealed that this compound can impede the synthesis of uridine in mammalian cells. This inhibition may arise from its capacity to form a complex with the enzyme uridine phosphorylase, or it could be an indirect consequence of its impact on cellular energy metabolism.
