1. The authors measured the concentrations of lead and zinc protoporphyrin in blood. 2. Macroscopically, the cirrhotic liver can have a black color due to protoporphyrin deposits. 3. The light chains are glycosylated and contain the modified iron protoporphyrin IX active site. 4. Protoporphyrin IX is a biochemical widely used as a carrier molecule for divalent cations.5. Complexed with zinc-ions ( Zn 2 + ) it forms Zinc protoporphyrin . 6. The immediate precursor to haem is protoporphyrin IX ( PPIX ), an effective photosensitiser. 7. Defects in ferrochelatase create a buildup of protoporphyrin IX, causing erythropoietic protoporphyria ( EPP ). 8. Exposure to lead also can be evaluated by measuring erythrocyte protoporphyrin ( EP ) in blood samples. 9. The examination of liver tissue under a Wood s lamp reveals a red fluorescence due to protoporphyrin . 10. Thus, the two products are S-adenosylhomocysteine and magnesium protoporphyrin IX 13-methyl ester.
