Lipase Lab

Explore how lipase breaks down fat. Compare two test tubes and watch what happens when one receives lipase.

6 drags · one simulated experiment
TODAY’S AIM

Study the effect of the presence of lipase on lipid digestion.

Compare the colour of the two mixtures after five minutes.

What you’ll do

  1. PrepareAdd the same milk, detergent, sodium carbonate solution and indicator to A and B.
  2. WarmUse the same 37°C water bath for both test tubes.
  3. Add lipaseAdd lipase to B. A gets the same volume of water as the control.
  4. ObserveWatch the mixture colours for five simulated minutes.

What goes in each test tube?

Both: 5 mL milk + 1 mL detergent + 1 mL prepared sodium carbonate solution + 1 mL prepared phenolphthalein indicator.

A Control · without lipase

1 mL distilled water

B With lipase

1 mL lipase solution

Both finish with 9 mL in a 10 mL test tube.

Follow the glowing item. Incorrect steps have no effect. Music and sounds can be muted.
