Amino Group

An amino group is a chemical structure found in many organic compounds, especially amino acids—the building blocks of proteins. It consists of a nitrogen atom attached to two hydrogen atoms (NH₂). This group plays a key role in biological systems, enabling amino acids to connect and form proteins. The amino group is basic, meaning it can accept a hydrogen ion (proton), which influences the molecule's chemical behavior and interactions. Its presence is essential for the structure and function of living organisms, contributing to processes like enzyme activity, cell signaling, and metabolic reactions.
