oxidize

This process poses challenges including selective addition of bromine at the ortho position, difficulty working with certain chemical groups, and the tendency of o-bromobenzenethiols to oxidize easily in air releasing unpleasant odors.

Exposure to air oxidizes the metal sulfides in bedrock, releasing the metals into groundwater, which flows into surface streams.

Bella moths are able to avoid the ill effects of pyrrolizidine alkaloids by using a special enzyme that oxidizes the molecule, rendering it harmless.

Outside the laboratory, other oxidizing pollutants such as nitrogen oxides, which cannot be tested in laboratory experiments because of their toxicity, can amplify the effect of ozone.

There is evidence that these bacteria gain energy by reducing highly oxidized forms of sulfur to less oxidized ones.
