Antioxidation

Part of speech: noun

Definitions

1. The process of preventing or slowing damage caused by reactive oxygen species or free radicals in cells or materials ; a chemical or biological action that inhibits oxidation ; protection mechanism that preserves integrity by counteracting oxidative effects
2. A mechanism that reduces or stops the chemical reaction involving oxygen that causes deterioration or damage ; an intervening process that neutralizes or limits free radical activity ; a defense against harm triggered by oxidative stress in living organisms or substances
3. An action or process that blocks or reduces the effect of oxidation that leads to cellular or material decay ; the capability of substances to protect against oxidative injury ; a preventative function that minimizes damage caused by oxidative molecules and radicals

Etymology: Antioxidation is a plain technical formation: the prefix "anti-", meaning "against" or "opposed to", attached to "oxidation", the process by which a substance combines with oxygen and tends to decay or change. Put together, the word names the act of preventing that combination, which is why it is used in chemistry and in discussions of how materials such as fats, rubber and food are kept from spoiling. The prefix does most of the work here. "Anti-" comes from Greek "anti", and it has been used freely in English to form words that mean the reverse of, or a block against, the base term. Its pairing with "oxidation" follows the same pattern as older coinages like "antiseptic" and "antifreeze", where the prefix signals a counteracting process rather than a thing.

Synonyms: oxidation prevention, antioxidant protection, oxidant inhibition, oxidation resistance, oxidative protection

Antonyms: oxidation, rusting, corrosion, oxidative damage
