1 Proteins Revision L.O: To recall info on proteins To identify and correct any misconceptions Starter: Q) Polypeptides such as spectrin are formed from amino acids. Describe the structure of an amino acid molecule and explain how amino acids link together. 6 marks

2 Mark Scheme 1.Amino acid based on carbon with four groups attached; 2.Amino/ NH2 and carboxyl/ COOH; 3.R-group/ side chain + hydrogen; 4.R-group differs from one amino acid to another; 5.Amino acids joined by condensation; 6.Bond formed between NH2 and COOH; 7.Involves removal of molecule of water; 8.H from NH2 and OH from COOH;

3 What Do I Need to Know? Structure of an amino acid Formation of a polypeptide Functions of proteins Levels of protein structure Application of knowledge to ‘unknown scenarios’ Increasing in knowledge

4 Protein Structure

5 Activity Options:  Pasta poster  Past exam questions  ‘If I Am the Answer…’ worksheet / glossary  Revision mindmap
