Where does the structure of our body come from? This unit looks at the structure of cells and how proteins are used by both animals and plants to create a framework for cellular growth. You will also learn how a material as fine as spider silk can exceed the strength of steel.
After you have completed this unit you should be able to:
- describe and give examples of how self-assembly enables construction ‘from the bottom up’ in natural materials;
- explain what is meant by primary and higher-order structure in proteins and give examples;
- give examples of the range of functions carried out by proteins within cells;
- describe how a combination of strong and weak bonding within biopolymers and lipids is used to build hierarchical structures with common structural elements and finely tuned properties, including calculations where appropriate;
- explain how both positive and negative design principles must be applied to the design of molecular devices and comment on the challenges involved in attempting such design.
