  • When lactose enters the body, it's cleaved by the enzyme lactase into glucose and galactose via a process known as hydrolysis. Once lactose has been cleaved into glucose and galactose, those two simple sugars can be absorbed by the body and used as en
  • You can buy lactose, lactase (Lactaid), and a diabetic glucose monitor for around $50 total. Lactose is converted to glucose with lactase. The detection limits of glucose monitors are 10-20 mg/mL. Lactose is soluble in water at 195 mg/mL. With this gear, you can make some kinetic plots at different temps to show the maximum enzymatic rate at 37 ...
  • Lactase is an enzyme that is produced in the small intestine. This enzyme works to break down lactose (the sugar in milk) into simple sugars. Although we know that amylase works on starch and that lactase works on lactose, we want to know if these enzymes can work on other substrates as well. Develop a detailed procedure, including the ...
