Levels of Protein Structure is a part of the VCE Biology area of study ‘How do Cellular Processes Work?’ and subtopic ‘Nucleic Acids and Proteins’. There are four levels of protein structure. These are:
- Primary structure: the sequence of amino acids linked in a chain
- Secondary structure: the hydrogen bonding of the peptide backbone causes the amino acids to fold into a repeating pattern
- Tertiary structure: a three-dimensional folding of a protein due to side chain interactions
- Quaternary structure: a structure of more than one amino acid chain
