A carbonyl is either a ketone or an aldehyde. In order to see whether the carbonyl group is present (C double bond O), 2,4-dinitrophenylhydrazine must be used. If an orange/yellow precipate is formed, ...

A condensation reaction is where two small molecules react together to form a larger molecule with the elimination of a small molecule like water. Two amino acids can react in a condensation reaction t...

Amino acids are amphoteric which means they can act as an acid or a base.

An isoelectric point is the pH at which an amino acid exists as its zwitterion. A zwitterion is the dipolar ionic...

All amino acids except glycine are chiral molecules. This is also known as optical isomerism.

This means that they form isomers that are non-superimposable mirror images of each other. Wh...

Amino acids are the monomers that form peptides and proteins. There are 20 different amino acids that contain an amino group (NH₂), carboxyl group (COOH) and R-group. The general formula is:...
