Learning Outcomes

On successful completion of this module students should be able to:

1. Identify and describe the structures of biological molecules.

2. Explain the purpose and basis of methods used to analyse biological material.

3. Perform calculations to determine amounts of substances and concentrations.

Brief description

To study the complexity of a living organism the chemistry of molecules and pathways within its cell(s) must be recognised. This module will develop the concept that the structure and function of biological molecules is a consequence of their chemistry. The skills required to calculate how to prepare chemical solutions such as biological growth media and buffers required for a wide range of biological work will be developed, along with an outline of spectroscopic methods used for biological measurement.


The course will start with a consideration of DNA and how its structure and function are a consequence of nucleotides paired by hydrogen bonding. The role of the cell membrane in forming the boundary between the living cell and its environment will be used to introduce lipids. Functional groups in amino acids and monosaccharides will lead to consideration of structures of proteins and polysaccharides and their investigation by spectroscopic methods.
The concepts of moles and molar concentrations will be introduced together with Avogadro's constant and calculations for making up solutions of known concentration. The carboxyl and amino functional groups will be dealt with in the context of acids, bases and buffers.

Module Skills

Skills Type Skills details
Application of Number Workshops will involve calculations relevant to the course material including determining amounts, concentrations, volumes and balancing equations.
Improving own Learning and Performance Outside the formal contact hours students will be expected to practice with directed learning exercises on which feedback will be available.
Information Technology
Personal Development and Career planning
Problem solving Lectures will introduce problem solving with worked examples and directed study will provide students with an opportunity to practice these skills. Workshops will extend this work and will be assessed.
