Summary
Lipid autoxidation research has overlooked epoxides, crucial reactive intermediates. Accounting for these overlooked epoxide products is essential for understanding lipid oxidation
Area of Science:
- Biochemistry
- Oxidative Stress Research
- Food Chemistry
Background:
- Lipid oxidation is a well-studied process, yet critical aspects remain unclear.
- Epoxides, products of lipid autoxidation, have been historically underestimated.
- Underestimation impacts analysis, understanding of function, and consequences in various systems.
Purpose of the Study:
- To highlight epoxides as critical, overlooked products of lipid autoxidation.
- To explain historical reasons for the underestimation of epoxides.
- To advocate for increased research into epoxide formation, detection, and reactivity.
Main Methods:
- Review of reactions generating lipid epoxides during autoxidation.
- Outline of limitations in current methods for detecting and tracking epoxides.
- Discussion of historical context influencing epoxide research.
Main Results:
- Epoxides are functionally active and competitive intermediates in lipid oxidation.
- Limitations in detection methods contribute to the underestimation of epoxide presence.
- Epoxides significantly impact other molecules and cellular functions.
Conclusions:
- Epoxides must be accounted for to accurately determine the state of lipid oxidation.
- Recognizing epoxides is vital for tracking the consequences of lipid oxidation in oils, foods, and tissues.
- Further research using contemporary analyses is needed to elucidate epoxide roles.

01:20Radical Autoxidation
2.1K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

02:23Autoxidation of Ethers to Peroxides and Hydroperoxides
7.6K
Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.

12.8K
Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

01:17Oxidation of Phenols to Quinones
3.1K
In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...

Overview
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of...

02:04Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
5.8K
Diols are compounds with two hydroxyl groups. In addition to syn dihydroxylation, diols can also be synthesized through the process of anti dihydroxylation. The process involves treating an alkene with a peroxycarboxylic acid to form an epoxide. Epoxides are highly strained three-membered rings with oxygen and two carbons occupying the corners of an equilateral triangle. This step is followed by ring-opening of the epoxide in the presence of an aqueous acid to give a trans diol.
