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