Most inorganic acids are also weak but a few are strong. Inorganic acids can also be called mineral acids.
Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the Î± carbon. Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the Î± carbon. The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their side chains.
