In chemistry, especially in organic chemistry and biochemistry, an amino group is an ammonia-like functional group composed of a nitrogen and two hydrogen atoms covalently linked.

-₂

It is a basic functional group that can give the free electron pair of the nitrogen atom to a proton. In this process, it becomes positively charged and turns into -NH₃⁺.

A compound containing an amino group is called an amine.
