Work Step by Step
The basic structure of amino acid has a hydrogen atom, an amine group, carboxylic group and an R group attached to a carbon atom. The presence of amine and the carboxylic group makes it an acid-base nature. When dissolved in water, a zwitterion is formed. The carboxylic group in Lysine loses hydrogen and is transferred to the amine group.
This makes one end positive and the other end negatively charged, resulting in an overall of no charge. This makes Lysine polar.
COOH -> $COO{-}$
$NH_{2}$ -> $NH_{3}$ +
