WebZinc protoporphyrin (ZPP) concentrations are widely used as biomarkers for lead toxicity. Ferrochelatase is another crucial enzyme that catalyzes the insertion of iron into protoporphyrin IX. However, in the cases of Pb toxicity, this enzyme is inhibited and the pathway is interrupted.
http://www.clinlabnavigator.com/zinc-protoporphyrin.html WebLead inhibits the enzyme ferroche-latase, which catalyzes the insertion of iron into the protoporphyrin mol-ecule, which then becomes heme. If iron is not inserted into the …
WebThis test is recommended for screening patients for possible erythropoietic protoporphyria and X-linked dominant protoporphyria. In addition, it can be used for evaluation of iron-deficiency anemia and chronic lead intoxication. Testing begins with total erythrocyte porphyrins. If the result is below 80 mcg/dL, it is normal, and testing is ...
WebZinc protoporphyrin reflects the toxic effects of lead on an erythrocyte enzyme system. Levels usually begin to rise when the blood lead level exceeds 40 μ g/100 mL. Once … crane co newsWeb1 jan. 2000 · Zinc is an alternative metal substrate for ferrochelatase and can be incorporated into protoporphyrin, forming zinc-protoporphyrin (ZnPP) [19], which is far less phototoxic than metalfree ... crane cookware ccasseroleWebObjective: To assess the relationship of blood lead and hemoglobin, zinc protoporphyrin, and ferritin concentrations in children.
