Worked practice questions

Amino acids contain an amino group along with a/an:

  1. carboxyl (acidic) group
  2. hydroxyl group only
  3. aldehyde group
  4. phosphate group
Show answer and solution

Correct answer: A. carboxyl (acidic) group

An amino acid has an amino (–NH₂) group and a carboxyl (–COOH) acidic group on the α-carbon.
