oxidize

Bacteria, fungi, and plants use this enzyme to oxidize alcohols.

This suggested that microscopic plankton living on the surface of the seas produce sulfur in the form of a gas, dimethyl sulphide, that once in the atmosphere, oxidizes and forms small particles called aerosols.

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.
