By their side chains. All amino acids have this structure:

HOOC- C - NH2

Attached to that middle C is the side chain. They can have many different properties-

They can be aromatic, polar, lipophilic, basic, acidic, Sulfur containing, among others

There are 20 amino acids inside the human body, each has a different structure and function, due to its properties.

Amino acids are divided into two groups, essential amino acids and nonessential amino acids. Nonessential amino acids can be made or constructed by the body whereas essential amino acids need to be added to a diet in order for the body to have them.

What is the theoretical number of chemically different dipeptides that may be assembled from 12 different types of amino acids?

the answer is C (144). The working is: 12^2 = 144. Here 12 is the no. of different amino acids and 2 is the no. of amino acids in the chain (its a dipeptide so, 2 amino acids).
