Tonight's homework is to complete Classwork 96, as well as Classwork 95 (if not finished in class). Below is some background information about the enzyme bromelain.
Useful Information about Bromelain
Bromelain is a mixture of enzymes found naturally in the juice and stems of pineapples. Called a proteolytic enzyme, bromelain is believed to help with the digestion of protein. Pineapple has been used for centuries in Central and South America to treat indigestion and reduce inflammation. Bromelain, which is derived from the stem and juice of the pineapple, was first isolated from the pineapple plant in the late 1800s. Bromelain can be used to treat a number of conditions, but it is particularly effective in reducing inflammation from infection and injuries.
The optimum pH value seems to be between 4 and 6, but Bromalein is still functional in a solution with a pH between 3 and 8. Once it has combined with its substrate, the activity is no longer susceptible to the effect of the pH.
A temperature range from 45-65°C is regarded favorable for the digestive process and 62°C as the optimum point. Its activity decreases at 70°C or higher.
