WebLead can hinder heme-synthetase (an enzyme responsible for assimilating iron into protoporphyrin 9), whereby zinc is substituted into protoporphyrin 9 in the place of iron and therefore may... Web1 jan. 2005 · Lead (Pb) exposure compromises heme synthesis by inhibiting ferrochelatase, forming zinc-protoporphyrin (ZnPP). This study aims to validate a method for the determination of ZnPP by HPLC with ...

WebTest Zinc Protoporphyrin; Common Abbreviations: ZPP: Profile: NA: Tube type: EDTA: Clinical Indication: Monitoring lead toxicity and occasionally for the investigation of anaemia 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 molecule, then zinc, having a greater affinity for protoporphyrin, takes the place of the iron, forming ZPP.1 Concentra-tions of ZPP rise in iron deficiency how many baseball games in a season in 1929
