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

Step 1 Step 1 is the synthesis of aminolevulinic acid. Succinyl coenzyme A (CoA) and glycine condense (in the presence of pyridoxal phosphate ) forming delta … Biliverdin results from the breakdown of the heme moiety of hemoglobin in erythrocytes. Macrophages break down senescent erythrocytes and break the heme down into biliverdin along with hemosiderin, in which biliverdin normally rapidly reduces to free bilirubin.
