Unit 4 Q4c 3.3.13.2 Proteins. Know the structure of proteins. Understand how peptide links can be hydrolysed to release amino acids. Know how to use chromatography to separate and identify amino acids. Draw structures of a peptide formed from up to three amino acids, and of amino acids formed by hydrolysis of a peptide. Identify primary, secondary and tertiary structures in diagrams and explain how these structures are maintained by hydrogen bonding and S–S bonds. Calculate Rf values from a chromatogram. Students make models of dipeptides and then hydrolyse them. Students draw structures of a range of tripepetides.
