Overall aims and purpose
The major aim of this module is to advance students' knowledge of biological chemistry, highlighting the cross-disciplinary nature of this area. Both, bioinorganic and bioorganic aspects will be discussed. A particular emphasis will be on the understanding of the role of biologically active compounds (e.g. enzymes and proteins, lectins, [complex] carbohydrates, and other biopolymers) in biological systems on molecular level, how to study and analyse such systems. Examples will be given to illustrate links to health and disease. This module is suitable for students with fundamental knowledge (approx GCSE level) of Chemistry and fundamental knowledge (approx GCSE) of Biology.
This course comprises two main topics and an introduction to some related chemical principles (beyond GSCE).
Glycobiology – This section will introduce the role of carbohydrates in biological systems. Starting from basic concepts and terminology specific for carbohydrate chemistry, the following areas will be illuminated: properties and structures of common polysaccharides (e.g. amylose, cellulose, chitin, chitosan, peptidoglycans, pectins, dextrans, glycosaminoglycans, proteoglycans), chemical and enzymatic synthesis and degradation, complex carbohydrates (case studies: human and bacterial structures), glycoconjugates (case studies: glycoproteins, glycolipids), carbohydrates in medicine (case studies: lead structure, vaccine, inhibitor), carbohydrate recognition (case studies: lectins) in e.g. inflammatory processes (immune system), protein folding, blood group typing.
Bio-inorganic Chemistry - This series of lectures will focus on the chemistry of metal ions in biological systems, particularly on the design of enzyme active sites with regard to their main biological roles. Bulk metals (Na, K, Ca and Mg) will be introduced but the main focus will be on important trace metals (e.g. Fe, Zn and Cu), and key ligand types (O, N and S-based ligands). There will be some information on characterisation techniques which are applicable to enzyme active sites and special topics (e.g. metal uptake/transport and/or biomineralisation).

SPECIFIC RESOURCE IMPLICATIONS FOR STUDENTS - None
Threshold (40%). Knowledge and understanding of the content covered in the course is basic; Problems of a routine nature are generally adequately solved; Transferable skills are at a basic level.
Good (~60%). Knowledge base covers all essential aspects of subject matter dealt with in the programme and shows good evidence of enquiry beyond this. Conceptual understanding is good. Problems of a familiar and unfamiliar nature are solved in a logical manner; solutions are generally correct and acceptable. Performance in transferable skills is sound and shows no significant deficiencies.
Excellent (>70%). Knowledge base is extensive and extends well beyond the work covered in the programme. Conceptual understanding is outstanding. Problems of a familiar and unfamiliar nature are solved with efficiency and accuracy; problem-solving procedures are adjusted to the nature of the problem. Performance in transferable skills is generally very good.
On successful completion of the module, the student will be able to: Understand some of the key roles in inorganic chemistry in biological systems.
On successful completion of the module, the student: should be able to apply basic carbohydrate chemistry terminology.
On successful completion of the module, the student: should be able to recognise and draw the chemical structure of common polysaccharides.
