WebHowever, PUFAs contain bis-allylic moieties with methylene groups flanked by C–C double bonds and the C–H bonds in such methylene groups are very weak; this structure nature renders PUFA-containing phospholipids susceptible to oxidation, particularly in an iron- and oxygen-rich cellular environment . If left unchecked, a lethal accumulation ... WebThe lipid peroxidation begins with the hydrogen peroxide (H 2 O 2) produced by POR/CYB5R1. H 2 O 2 reacts with ferrous ion to produce hydroxyl radicals, which can …
