Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
There are 20 different amino acids. They differ from one another because they all have different side chains.
Salts are the products of reactions between acids and bases.

Salts are formed by the reactions between acids and salts; a salt contain an anion from the acid and a cation from the base.
They differ from each other by the cognent that it is connected to.
the sequence of amino acids in the polypeptide chain differs from protein to protein -xbanditlover
They have different side chains.
They differ in some of the elements from which they are made and are:- 1 Carbohydrates 2. Lipids 3. proteins 4. Nucleic Acids
the subunits that proteins are made from are called amino acids , there are about 20 common amino acids that are used in the synthesis of proteins in humans , and proteins differ in the number , types , and sequence of amino acids .
In general, acids increase H+. Bases increase OH-. Example of a strong acid: HCL. Example of a strong base: NaOH.-- dana
