- amino acids – the monomers from which proteins are made from
- dipeptide – 2 amino acids joined together with 1 peptide bond
- polypeptide – Many amino acids joined together with peptide bonds
- primary structure]] – first structure of a protein. Chain of amino acids + order
- secondary structure – second structure of a protein. α-helix and β-pleated sheet
- tertiary structure – third structure of a protein. Folding of α-helix and β-pleated sheet into 3D structure
- quaternary structure – joining of tertiary structure proteins together into larger molecules
- enzyme – a protein molecule able to catalyse the break down / formation of molecules
- induced-fit model – the theory stating that the enzyme’s active site changes shape slightly when a substrate attaches
- lock and key model – the theory stating that the enzyme’s active site is rigid and never changes shape
