Superoxide (Noun)
Meaning 1
The univalent anion O2-; "much of the O2 supporting cellular respiration is reduced to the superoxide anion O2-".
Classification
Nouns denoting substances.
Examples
- In healthy individuals the cell protects itself against reactive oxygen species such as superoxide, which contains an unpaired electron.
- A superoxide is also produced whenever a redox reaction takes place in the body, resulting in cellular damage over time.
- The enzymes superoxide dismutase convert the superoxide into hydrogen peroxide and oxygen, reducing the amount of damage to cells.
- Mitochondrial DNA can be vulnerable to mutations from free radicals such as superoxide that are produced during normal metabolism.
- Superoxide anion plays a role in the pathogenesis of a number of diseases including heart disease, stroke and neurodegenerative disorders.
Synonyms
Meaning 2
A metallic oxide containing the univalent anion O2-.
Classification
Nouns denoting substances.
Examples
- Potassium superoxide is a highly reactive metallic oxide that readily releases oxygen when it comes into contact with water or moist air.
- The superoxide ion acts as a powerful oxidizing agent and can play a critical role in a wide variety of redox reactions.
- Potassium superoxide, an additive to a respirator canister filter or 'CHRISTMAS TREE', supplies additional breathing air and chemical air-purifying capabilities in the event of emergencies.
- Rubidium superoxide forms spontaneously by combining metallic rubidium and the elemental dioxygen when put under some applied external stimuli in several advanced production equipment operations for catalyst industries.
