How is heme metabolized into biliverdin

WebHow is heme converted to bilirubin? The metabolic system which converts heme to biliru- bin consists of microsomal heme oxygenase, which cat- alyzes the oxidation of heme at the a-methene bridge to form biliverdin, and biliverdin reductase, a soluble enzyme responsible for the reduction of biliverdin to bilirubin [16]. http://envismadrasuniv.org/Physiology/pdf/Bilirubin%20metabolism%20Applied%20physiology.pdf
