  2. Lipid peroxidation - Wikipedia

    en.wikipedia.org/wiki/Lipid_peroxidation

    Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, [1] resulting in the formation of peroxide and hydroperoxide derivatives. [2] It occurs when free radicals , specifically reactive oxygen species (ROS), interact with lipids within cell membranes , typically polyunsaturated fatty ...

  3. Chain reactions in living organisms - Wikipedia

    en.wikipedia.org/wiki/Chain_reactions_in_living...

    Chain reaction in chemistry and physics is a process that produces products capable of initiating subsequent processes of a similar nature. It is a self-sustaining sequence in which the resulting products continue to propagate further reactions. [1] Examples of chain reactions in living organisms are lipid peroxidation in cell membranes [2] and ...

  4. Oxidative stress - Wikipedia

    en.wikipedia.org/wiki/Oxidative_stress

    Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. [1]

  5. Isotope effect on lipid peroxidation - Wikipedia

    en.wikipedia.org/wiki/Isotope_effect_on_lipid...

    Mechanism of isotope effect on lipid peroxidation. An animated model of a chain reaction with slow, oxidation-resistant elements. PUFAs are highly prone to oxidative damage through a purely chemical, non-enzymatic chain reaction. With tight packaging of PUFAs in membranes, the oxidation of a single PUFA molecule rapidly leads to a chain ...

  6. Ferroptosis - Wikipedia

    en.wikipedia.org/wiki/Ferroptosis

    Ferroptosis. Appearance. Oxytosis/ferroptosis is a type of programmed cell death dependent on iron and characterized by the accumulation of lipid peroxides, and is genetically and biochemically distinct from other forms of regulated cell death such as apoptosis. [ 1 ][ 2 ] Oxytosis/ferroptosis is initiated by the failure of the glutathione ...

  7. Fatty acid degradation - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_degradation

    Fatty acid degradation. Fatty acid degradation is the process in which fatty acids are broken down into their metabolites, in the end generating acetyl-CoA, the entry molecule for the citric acid cycle, the main energy supply of living organisms, including bacteria and animals. [1][2] It includes three major steps: Lipolysis of and release from ...

  8. 4-Hydroxynonenal - Wikipedia

    en.wikipedia.org/wiki/4-Hydroxynonenal

    Infobox references. 4-Hydroxynonenal, or 4-hydroxy-2E-nonenal or 4-hydroxy-2-nonenal or 4-HNE or HNE, (C 9 H 16 O 2), is an α,β-unsaturated hydroxyalkenal that is produced by lipid peroxidation in cells. 4-HNE is the primary α,β-unsaturated hydroxyalkenal formed in this process. It is a colorless oil.

  9. Lipid metabolism - Wikipedia

    en.wikipedia.org/wiki/Lipid_metabolism

    Lipid metabolism. Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food and are synthesized by the liver. [1]
