BIOORGANIC CHEMISTRY AND DRUG DISCOVERY - 2021/2
Module code: CHE2037
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module builds on general organic chemistry knowledge in the context of biomolecules including proteins, carbohydrates, nucleic acids and natural products from common biosynthetic pathways. It covers the biomolecules’ natural and synthetic chemistry and uses this foundation to support a basic understanding of drug action and the drug discovery process.

|Assessment type||Unit of assessment||Weighting|
|Examination||Examination: 1.5 hours||80|
The assessment strategy is designed to provide students with the opportunity to demonstrate:
- application of knowledge and skills from lectures to answer problems or write essays on topics related to biomolecule identification, biosynthesis and medicinal uses
- use of knowledge from the course and, where necessary, further background reading to comprehend a drug discovery paper from the peer-reviewed literature and answer a set of questions on it
Thus, the summative assessment for this module consists of:
- one piece of coursework consisting of either an essay and/or question sets based on lecture material and the literature.
- examination (closed book)
Most lectures contain small problem-solving tasks which are addressed in groups of 2-3. During the task, the lecturer moves amongst the groups commenting and guiding the students’ starting points and answering strategies. Common problems are highlighted to the whole class and the final solution is given on the board/visualiser.
Feedback to the coursework will consist of comments on individual students’ work as well as general feedback document covering common misconceptions and mistakes.
- Develop an understanding of biomolecules and natural products
- Describe how drugs interact with biomolecules and gain a critical understanding of the drug discovery, design and development process

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
introduce chemists to drug discovery and provide them with foundational knowledge and understanding of biomolecules for understanding more advanced drug discovery concepts and biochemistry in the future.
The learning and teaching methods include:
- lectures which incorporate small-group problem-solving (32 h)
- coursework which requires application of course material and further research into topics or questions related to course content
- revision tutorials which address students’ issues which arise during revision (2 h)
- written examination 1.5 h
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
