Amino acid

Amino acids are the building blocks (monomers) of proteins. 20 different amino acids are used to synthesize proteins. The shape and other properties of each protein is dictated by the precise sequence of amino acids in it.

Amino acids are the building blocks of proteins.
Twenty of the amino acids are used to make protein. Each has a carboxyl group (COOH) and an amino group (NH2).
Each amino acid is different and therefore has its own unique properties.
