Enzymes are nature's catalysts.  They act to speed up biochemical reactions to make them useful for metabolism in living organisms.  However, since they are complex polypeptides, enzymes can be denatured by shifts in temperature and pH, and this in turn can affect the way they work.  Participants in this workshop will experiment with a range of enzymes including amylase, trypsin, lipase, rennin and urease to compare their reactions and discuss their suitability for student experiments.  We will also look into troubleshooting enzyme reactions and using a datalogger to measure reaction rates where possible.
