Catalase enzyme is one of the first enzymes to be purified and analyzed. Methods of data analysis had to be developed along with developing an understanding of how to study and preserve enzyme activity!

Graphical Analysis has long been the method of choice for scientists trying to figure out how enzymes work (basic mechanisms of action).

Catalase is a widely present enzyme whose function is to destroy peroxides, which are poisonous and highly reactive. Recently, scientists have found some cool applications for catalase:

neutralizer for chemical disinfection of contact lenses --- scroll to Claim Item 15.
bleaching a billion pairs of blue jeans to make them look old, etc.
may prolong life!
