amino group

An amino group is a functional group in chemistry characterized by a nitrogen atom bonded to hydrogen atoms or alkyl/aryl groups. Amines, which contain amino groups, are common organic molecules and are valuable for their basic properties, as they can accept hydrogen atoms from acidic molecules.12

Amino acids are organic molecules that contain a basic amino group, an acidic carboxyl group, and a unique organic R group. They function as the building blocks of proteins, which are essential for catalyzing chemical reactions, providing structural elements, and binding cells together. The properties of proteins are determined by the properties of their constituent amino acids.345
