Biological synthesis of heme b
WebHeme synthesis is described in eight steps. Glycine and succinyl-CoA are the starting materials; succinyl-CoA is an intermediate of the Krebs cycle, and glycine can be derived from the diet or from serine. The first step in heme synthesis is catalyzed by … WebAbstract. Heme synthesis starts in mitochondria with the condensation of succinyl-CoA with the amino acid glycine, activated by pyridoxal phosphate. ALA synthase is the rate …
