coerulea can produce the blue pigment, biliverdin IX[alpha], and provide transcript information about H.
It's tempting to wonder if evolution has favored green blood because toxic biliverdin might make predators spit out any lizard they start to bite.
HO-1 induction results in degradation of prooxidant heme, releasing iron, carbon monoxide (CO), and biliverdin; biliverdin is converted to bilirubin, an antioxidant; iron is sequestered by ferritin; the products of the HO-1 reaction have antioxidant, anti-inflammatory, vasodilatory, and antiapoptotic effects, leading to attenuation of CIN [24].
In a previous study, it has been shown that bilirubin undergoes redox cycling with biliverdin, which is subsequently reduced by biliverdin reductase to regenerate bilirubin (63).
The "haem" bit of the haemoglobin contains a single atom of iron, which goes through many transformations as it gets broken down, through bilirubin and biliverdin.
This green pigment was suggested to be biliverdin which has now recently been shown to be bilirubin.
It is based on oxidation with oxygen to the green biliverdin catalysed by bilirubin oxidase (BOX).
Biliverdin is then processed to form bilirubin (see figure 1, opposite page).
The reticuloendothelial system catabolizes hemoglobin into free iron, globin, and biliverdin, which is rapidly converted to bilirubin.
It is made by enzymes breaking down the red haem molecule (found in haemoglobin in red blood cells) into green biliverdin and yellow bilirubin molecules.
