Module Aims
  • To give a basic understanding of the structures, properties and functions of the main types of biological molecules: proteins (including enzymes), carbohydrates and lipids.
  • To outline the main pathways of metabolism in the cell: catabolic (breakdown) reactions yielding energy and anabolic (biosynthetic) reactions leading to new structures within the cell.


Learning Outcomes

On completion of this module, the student will be able to:

§           Outline the monomer-polymer principle in relation to a variety of biological macromolecules

§           Describe systematic classification schemes for biomolecules

§           Discuss the various classes of biological macromolecules with respect to their regulation and function

§           Outline the principles of enzyme catalysis, enzyme kinetic parameters and some of their applications

§           Explain the unifying principles underlying the complexity of cellular metabolism

§           Describe in detail the metabolic fate(s) of each class of biomolecule

§           Outline the role of cellular metabolism and related biomolecules in human health and disease.
