Amine group

Definition

An amine group is a functional group containing a nitrogen atom bonded to one or more hydrogen atoms. It plays a crucial role in the structure and function of amino acids and proteins.

5 Must Know Facts For Your Next Test

1. Amine groups are essential components of amino acids, the building blocks of proteins.
2. The basicity of amine groups can affect protein folding and enzyme activity.
3. In aqueous solutions, amine groups can accept protons, making them important in buffering systems.
4. Primary amines have one carbon-nitrogen bond, while secondary and tertiary amines have two and three, respectively.
5. Amines can undergo reactions such as alkylation and acylation, which are significant in modifying protein structure.
