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, … See more 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 and a fatty … See more The fatty acid radical is not a very stable molecule, so it reacts readily with molecular oxygen, thereby creating a peroxyl-fatty acid radical. This radical is also an unstable species that reacts with another free fatty acid, producing a different fatty acid … See more If not terminated fast enough, there will be damage to the cell membrane, which consists mainly of lipids. Phototherapy may cause hemolysis by rupturing red blood cell cell membranes in this way. In addition, end-products of lipid peroxidation may be See more • Autoxidation • Rancidification See more 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 … See more The end products of lipid peroxidation are reactive aldehydes, such as malondialdehyde (MDA) and 4-hydroxynonenal (HNE), the second one being known also as … See more Certain diagnostic tests are available for the quantification of the end-products of lipid peroxidation, to be specific, malondialdehyde (MDA). The most commonly used test … See more WebJul 20, 2016 · According to the commonly held paradigm, the mammalian brain does not really use long-chain fatty acids (LCFA, C 12 –C 18) as fuel in the energy metabolism (for reviews 1–3).The only exceptions known so far are specialized mammalian hypothalamic neurons. 4 Moreover, neuronal mitochondria have been hypothesized to oxidize fatty … istar meaning in english
