WebMost of the ·OH generated in vivo comes from iron‐dependent reduction of H2O2 [4, 5]. Supporting too much iron as a free radical‐generating culprit in the risk of cancer, NHANES I data indicated that high body iron stores, manifested by increased transferrin saturation, are associated with an increased cancer risk [6]. WebIron plays a detrimental role in free radical-mediated oxidations, such as lipid peroxidation, by several mechanisms. In the initiation step, iron can serve as a catalyst for generating …
WebA free radical is an atom, molecule, or compound that is highly unstable because of its atomic or molecular structure (i.e., the distribution of electrons within the molecule). As a result, free radicals are very reactive as they attempt to pair up with other molecules, atoms, or even individual electrons to create a stable compound. WebJul 29, 2024 · Free radicals are compounds that can cause harm if their levels become too high in your body. They’re linked to multiple illnesses, including diabetes, heart disease, and cancer.
