Proteins - A Level Biology 

This video covers the following:
● Know the structure of an amino acid (structures of specific amino acids are not required).
● Understand the formation of polypeptides and proteins (as amino acid monomers linked by peptide bonds in condensation reactions).
● Understand the role of ionic, hydrogen and disulphide 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.
