The importance of chemistry to understand the inner workings of biology has led to the emergence of the field of chemical biology. In recent years, the development of cutting-edge synthetic methods, as well as analytical and imaging technologies, have underpinned advances in drug discovery, diagnostics, genome sequencing and biocatalysis. In this unit, you will learn how chemical structure and reactivity underpins the function of all nature’s biomolecules, from the enzymes that enable chemical reactions to occur inside cells, to the DNA featuring chemical modifications that affect how the genetic code is read. You will also learn how the development and application of modern synthetic chemistry can be used to generate designer biomolecules to perturb, manipulate and visualise cellular processes. Key examples include how we can synthesise an entire protein using synthetic chemistry alone, and how we can use fluorescent dyes to observe what is happening in live cells as a result of disease. You will gain insight into the rapidly advancing field of chemical biology, and how new chemistry-based technologies are being used to solve major problems in biology and medicine. Advanced students attend in addition an advanced seminar series to gain more in-depth disciplinary knowledge where they actively engage with a diverse range of contemporary chemical research problems and case studies. They gain additional opportunities to develop skills in collaborative work and enhance their written and oral communication skills.
