Verified step by step guidance

Identify the structure of an amino acid, which typically includes a central carbon atom (alpha carbon) bonded to four different groups: an amino group, a carboxyl group, a hydrogen atom, and a variable R group (side chain).

Understand that a functional group is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.

Recognize that the carboxyl group is a functional group with the structure \( \text{COOH} \), which is commonly found in amino acids. It is responsible for the acidic properties of amino acids.

Compare the given options: Aldehyde group (\( \text{CHO} \)), Ether group (\( \text{R-O-R'} \)), and Ketone group (\( \text{RC(=O)R'} \)) with the carboxyl group to determine which is present in amino acids.

Conclude that the carboxyl group is the correct answer as it is a fundamental component of amino acids, contributing to their acidic nature and ability to form peptide bonds.
