hydroxyl

Alcohol's functional group

Hydroxyl refers to a chemical group consisting of one oxygen atom bonded to one hydrogen atom (–OH).

This functional group appears throughout chemistry and biochemistry, defining alcohols and contributing to the properties of countless organic molecules.

A hydroxyl radical is a highly reactive form that plays roles in atmospheric chemistry and cellular damage.

The hydroxyl group makes the molecule water-soluble.
