Definition of autoxidation in English:

autoxidation

noun ˌɔːtɒksɪˈdeɪʃ(ə)nˌɔdəˌɑksəˈdeɪʃ(ə)n

mass nounChemistry

Spontaneous oxidation of a substance at ambient temperatures in the presence of oxygen.
〔化〕自氧化
Example sentencesExamples
- Many fatty foods are susceptible to autoxidation, involving the oxidation of lipid molecules to produce malodorous ketones, alcohols and acids that adversely affect the texture, flavour and taste of food.
- In the absence of melanin, the ascorbic acid undergoes metal-catalyzed autoxidation.
- Vitamin E is a chain-breaking antioxidant, i.e. it is able to repair oxidizing radicals directly, preventing the chain propagation step during lipid autoxidation.
- Lipid oxidation is a major cause of meat quality deterioration, as products of autoxidation of unsaturated fatty acids affect wholesomeness and nutritional value.
- It can also be formed by oxidative deoxyribose breakdown or autoxidation of sugars, such as glucose, and it plays a role in the pathophysiology of diabetes and ageing.

Derivatives

autoxidize

verb ɔːˈtɒksɪdʌɪzɔˈtɑksəˌdaɪz

[no object]

Chemistry

(of a substance) undergo autoxidation.
commonly used fragrance substances autoxidize on contact with air
Example sentencesExamples
- Thus reaction further autoxidizes to produce free radicals, hydrogen peroxide and hydroxyl radicals.
- In view of therapeutic strategies indole-type substances are to be preferred, as these are devoid of autoxidizing reactions as found with phenolic antioxidants like tocopherol.
- However, the oxy complex has the potential to autoxidise to form the ferric haemoglobin.
