Understand the role of ionic, hydrogen and disulfide bonding in the structure of proteins.

Understand the significance of the primary, secondary, tertiary and quaternary structure of a protein in determining the properties of fibrous and globular proteins, including collagen and haemoglobin.

Understand how the structure of collagen and haemoglobin are related to their function.
