Hi everyone

Amino acids are acids on one hand, and a base on the other hand.

<h3>What is an acid?</h3>

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group -NH_2 and a carboxylic group -COOH.

The carboxylic group ionizes such that:

COOH -- > COO^- + H^+

The presence of the amine group enables amino acids to also act as a base.
