Biliverdin

 

C33H34O8N33, a bile pigment; molecular mass 582.67. Green crystals. Biliverdin is an intermediate product of the decomposition of hemoglobin that occurs in macrophages of the liver, spleen, and bone marrow of vertebrate animals with the formation of the so-called verdoglobin, which then breaks down and liberates globin, iron, and biliverdin. The reduction of biliverdin leads to the formation of bilirubin. Biliverdin is also found in invertebrates (worms, crustaceans, insects).
