The obtained results show that major flavonoids were present in higher concentrations in vegetative stage than flowering stage.
WebNov 11, 2024 · Increased ROS together with lipid droplet accumulation often resulted in lipid peroxidation 3,8,9. We further assessed lipid peroxidation using the BODIPY 581/591 C11 lipid peroxidation sensor (BD ... 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 … 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 … 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 … 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 "second messenger of free radicals" and major bioactive marker of lipid … See more Certain diagnostic tests are available for the quantification of the end-products of lipid peroxidation, to be specific, malondialdehyde (MDA). … 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".
