Module aims

This module aims to highlight the central importance of enzymes as catalysts in biological systems which are involved in the interconversion of all essential cellular metabolites (primary metabolites) and the production of many natural products of importance in medicine and agriculture. In addition this module aims to define the major classes into which secondary metabolites fall according to their structure and to explain how labelled precursors can be used to determine the primary metabolic building blocks from which secondary metabolites are assembled. The module includes descriptions of the molecular mechanisms of the most important enzyme catalysed reactions in natural product biosynthesis and associated coenzyme mechanisms, and some of the methods used to elucidate these mechanisms. Students will learn how the principles of organic chemistry can be critically used to discriminate between different possible mechanisms for a given enzyme catalysed reaction (12 lectures).

In addition this module aims to enable students to link fundamental components of the major classes of molecular interactions that play key roles in recognition processes. Semi-quantitative methods for estimating strengths of these processes will be introduced and used in the analysis and study of well-described systems from biology (enzymes, drug-receptor interactions, non-covalent assemblies) and synthetic systems (small molecule, host-guest, self-assembled architectures). In studying these systems students will become familiar with underlying chemical principles and use some of the tools for computer-aided molecular visualisation and modelling encountered in years 1 and 2. The module is designed in particular to allow students working at the interface between Chemistry and Biology to begin to use these tools but is accessible to students on other Chemistry degree streams as well (10 lectures).
