Is lipid peroxidation good or bad
Did you know?
Lipid peroxidation is the chain of reactions of oxidative degradation of lipids. It is the process in which free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage. This process proceeds by a free radical chain reaction mechanism. It most often affects polyunsaturated fatty acids, … Zobacz więcej Initiation is the step in which a fatty acid radical is produced. The most notable initiators in living cells are reactive oxygen species (ROS), such as OH· and HOO·, which combines with a hydrogen atom to make water … Zobacz więcej The fatty acid radical is not a very stable molecule, so it reacts readily with molecular oxygen, thereby creating a peroxyl-fatty … Zobacz więcej The end products of lipid peroxidation are reactive aldehydes, such as malondialdehyde (MDA) and 4-hydroxynonenal (HNE), the second one being known … Zobacz więcej Certain diagnostic tests are available for the quantification of the end-products of lipid peroxidation, to be specific, malondialdehyde (MDA). The most commonly … Zobacz więcej When a radical reacts with a non-radical, it can produce another radical, which is why the process is called a "chain reaction mechanism". The radical reaction stops when two radicals react and produce a non-radical species. This happens only when the … Zobacz więcej If not terminated fast enough, there will be damage to the cell membrane, which consists mainly of lipids.

WitrynaSince lipid peroxidation is a self-propagating chain-reaction, the initial oxidation of only a few lipid molecules can result in significant tissue damage. Despite extensive …
WitrynaHence, the key metabolic event that triggers ferroptosis is iron-mediated lipid peroxidation (the process of oxidative destruction of lipids by free radicals). As a result, an increase in free radical production, fatty acid supply, and lipid peroxidation by certain enzymes is critical for ferroptosis [25].
