Question

Hi everyone

Answer 1

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

What is an acid?

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.
