Overall aims and purpose
To illustrate strategies to synthesise complex natural products and to apply concepts of retrosynthesis to strategic planning. Part of this is to advance students' knowledge of biological chemistry, highlighting the cross-disciplinary nature of this area. A particular emphasis will be on the understanding of the role of biological 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.
to illustrate strategic approaches to the total synthesis of selected natural products. One-third of the module introduces the students to a sub-discipline of natural products - glycobiology. It covers both chemistry and biology-related aspects.
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.

For students entering year 2 (level 5) after September 1st 2013 or MSc/MRes students, the threshold criteria are set as follows: Knowledge base is extensive and extends well beyond the work covered in the assignment; 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.
Students should be able to select appropriate techniques and procedures to execute the synthesis of complex organic molecules.
Students should be able to critically discuss the relationship of geometric and electronic structure of pi-conjugated systems, and to combine information from different physical methods to predict the properties of organic molecules and polymers. They should be able to explain physical-chemical principles of applications of pi-conjugated systems as materials for various organic electronic devices.
On successful completion of the module, the student: should be able to discuss general principles of carbohydrate recognition and its role in biological systems (e.g. cell-cell communication).
On successful completion of the module, the student: should demonstrate some fundamental knowledge about the role of carbohydrate recognition processes in health and disease.
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.
Teaching and Learning Strategy
This module includes 24 hours of lectures and tutorials, where active participation is required. It has been divided into three segments; one is on electronic structure and reactivity on conjugated PI-functional aromatic systems and another one is on for the synthesis of marine and terrestral natural products, the third one is an introduction to glycobiology. Private study 76 hours.
