A, Describe the structural features of an enzyme. Include reference to overall
structure and how it is stabilised by side chain reactions as well as describing the
active site (P4).
Enzymes are made up of proteins, wich are polymers of amino acids. They can get in
groups, to be abe to fo enzyme reactions.

Enzymes bind their substrates at active sites. The active site is the location on the surface of
the enzyme where the catalyzed reaction takes place. In the two views of lysozyme shown
above, the left panel shows a carbohydrate colored green bound to the active site of
lysozyme. The right panel shows the empty active site. Notice that the active site forms a
cleft on the enzyme surface designed to specifically interact with the substrate
