oxidative
Involving electron loss
Oxidative describes processes involving oxidation—chemical reactions where a substance loses electrons, typically by combining with oxygen.
The term appears most often in scientific contexts: oxidative stress refers to cellular damage from reactive oxygen molecules, while oxidative phosphorylation is how cells generate energy.
The oxidative breakdown of fats produces ketones.
