Zn protoporphyrin IX is formed not from heme but from protoporphyrin IX [PDF]
Meat Science, 2007 We examined the effects of exogenous myoglobin, a bivalent chelator, and nitrite on Zn protoporphyrin IX (ZPP) formation by using model systems. ZPP was formed in a model solution without addition of exogenous myoglobin. After incubation, the amount of ZPP in a model solution was increased but that of heme was not decreased compared with the amounts ...

A computational-first proof-of-concept for dual-function metal chelation and aggregate neutralization in an Aβ42 Drosophila model [PDF]
Frontiers in Aging NeuroscienceAlzheimer’s disease (AD) pathology is amplified by a self-reinforcing metal–Aβ–ROS axis, in which redox-active Cu and Fe bound to Aβ N-terminal histidines catalyze Fenton-like ROS generation and accelerate aggregation.
