The action of lipase AIM: Lipases hydrolize fats into glycerol and fatty acids1, therefor to investigate how different amount (1 cm3, 2 cm3, 4 cm3, 8 cm3, 12 cm3, 20 cm3) of 3% lipase solutions break down the fat in 5 cm3 of milk. RESEARCH QUESTION: how fast can different amount (1 cm3, 2 cm3, 4 cm3, 8 cm3, 12 cm3, 20 cm3) of 3% lipase solutions break down the fat molecules in 5 cm3 of milk? INDEPENDENT VARIABLE: amount of 3% lipase solution (1 cm3, 2 cm3, 4 cm3, 8 cm3, 12 cm3, 20 cm3) DEPENDENT VARIABLE: the speed (measured in minutes) of hydrolizing fat molecules CONTROLLED VARIANLE: concentration of lipase solution, amount of milk, amount and concentration of sodium carbonate solution HYPOTHESES: • lipase hydrolize fats into glycerol and fatty acid1 therefore as the amount of lipase is increased, the fat molecules will be hydrolized faster and faster • boiled lipase will not...
