Learning outcomes - after studying this topic, you should be able to:

• predict whether the acid and amine groups in amino acids will be protonated at different pH values
• predict the pI of amino acids and simple peptides
• describe the primary, secondary, tertiary and quaternary structure of proteins
• predict the products of hydrolysis of simple peptides
• appreciate the possibility of tautomerism in heterocycles
• describe the structural building blocks of RNA and DNA
