There are 22 different amino acids. What part of each amino acid is differnt from the others

Amino acids are units or building blocks of protein. These are crystalline solid without any colour and are soluble in water and insoluble in the organic solvent. All amino acids have five basic parts. These are a central carbon (C) atom, hydrogen(H) atom, an amino group (NH2) with one nitrogen atom and two hydrogen atoms, a carboxyl group (COOH) having one carbon atom, two oxygen atoms, and one hydrogen atom and an R-group or side chain. There are 22 different types of amino acids. They are different due to the different side chain or R-group. For example, if the side chain is H, the amino acid is Glycine and if side chain is CH3, the amino acid is Alanine
