oxidation
OK-si-DAY-shun
/ˌɒksɪˈdeɪʃən/
The process or result of oxidizing or being oxidized; in biology, the process by which cells break down food molecules to release energy.
In a kitchen, oxidation makes apples turn brown; in a cell, it's how we 'burn' fat for fuel.
The story behind the word. Originally coined to describe reactions involving oxygen. Later, chemists realized it's actually about the loss of electrons, but the name stuck because oxygen is the most common 'electron-stealer' in nature.
Word relationships
- combustion: Combustion is rapid oxidation that produces fire; biological oxidation is slow and controlled.
- reduction: The gain of electrons (the chemical opposite of oxidation).
Word family
- oxidize (verb): To undergo or cause to undergo oxidation.
- antioxidant (noun): A substance that inhibits oxidation.
Collocations
- fat oxidation
- cellular oxidation
- oxidative stress
Example sentences
- "Fat oxidation increases during low-intensity aerobic exercise, as the body uses stored lipids for fuel." Metabolic health
- "Rust is a common example of the oxidation of iron." Chemistry
Memory hook
Oxidation: Oxygen 'attacks' the molecule to release energy. Burning fuel with oxygen.
When not to use
Don't use as a synonym for 'breathing'; breathing brings in the oxygen, but oxidation is the chemical reaction that uses it.
Fun facts
- Antioxidants in foods like blueberries help prevent 'oxidative stress', which is essentially your cells 'rusting' from the inside.
