Answer for screen readers
The structure of serine is the first option: an amino group (NH2), carboxylic acid group (COOH), and a hydroxyl group (OH) on the beta carbon.
More Information
Serine is a non-essential amino acid with the chemical structure, including a hydroxyl group on the beta carbon. It is involved in protein synthesis and various metabolic processes.
Tips
A common mistake is confusing serine with cysteine, which has a thiol (-SH) group instead of the hydroxyl group.
