What is the structure of an amino acid?

Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

The universal structure of all amino acids is a central carbon atom that has a carboxyl group, an amino group, a hydrogen atom and an "R" side chain that varies from amino acid to amino acid bound to it. The carboxyl group consists of a carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl (-OH) group.
