Why it matters
This objective helps connect Amino acids and proteins (A-level only) to exam-style questions, flashcards, and revision notes for Amino acids, proteins and DNA (A-level only).
Quick student answer
Which of the following statements correctly describes the structure of amino acids?
Direct answer
Amino acids contain a hydroxyl group and a carboxylic acid group.
Key terms
- Amino acid: A molecule containing both an amine group (-NH2) and a carboxylic acid group (-COOH).
- Peptide bond: A covalent bond formed between the carboxyl group of one amino acid and the amino group of another.
Common trap
Confusing amino acids with other biomolecules: Remember that amino acids specifically contain both amine and carboxylic acid functional groups.
