Hydroxyl group | Definition, Structure, & Facts | Britannica
网页Hydroxyl group (―OH), in chemistry, a functional group with one hydrogen and one oxygen atom. An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the simplest and most common example. If one hydrogen atom is removed from a water molecule, a hydroxyl functional.

Hydroxyl Group - an overview | ScienceDirect Topics
网页Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom. They readily participate in hydrogen bonding, generating either a net positively or negatively charged ion. This group can also participate in chemical reactions to link molecules together, forming chains of sugars or fatty acids.
