Iron cleavage
WebApr 12, 2024 · Iron is essential for life. Many enzymes require iron for appropriate function. However, dysregulation of intracellular iron homeostasis produces excessive reactive oxygen species (ROS) via the Fenton reaction and causes devastating effects on cells, leading to ferroptosis, an iron-dependent cell death. In order to protect against harmful … WebThe average person contains about 4 grams of iron. Most of them in hemoglobin, in the blood.
