Concept introduction:

Amino acids:

• There are 20 most common naturally occurring amino acids.
• The substituent attached to the $\text{α-carbon}$ will be differ in amino acids.
• Different classifications of amino acids are present which includes aliphatic amino acids, basic amino acids, acidic amino acids etc.

Basic amino acids: Lysine and arginine are examples for two basic amino acids which contain two basic nitrogen-containing groups.

Lysine has an $\text{ε}-\text{amino}\text{group}$
