TRANSLUCENCY TEST FOR FATS
1. Lay a brown paper towel on the table
2. With an eyedropper, place 2 or 3 drops of water on the paper. You should have
a spot about the size of a quarter. Draw a circle around the spot and label it
“water”.
3. With an eyedropper, place 2 or 3 drops of vegetable oil on another part of the
paper. Draw a circle around the spot and label it “oil”.
4. Allow the spots to dry. Hold the paper up to the light and compare the area
inside the circles. Describe what you observe.
5. Choose a food to test. Predict whether the spot on the paper will be like the
water or the oil spot when it dries. Place a sample of the food on the paper.
6. Allow the spot to dry. Shake off any excess food and hold the paper up to the
light. Describe what you observe.
7. Repeat steps 5‐6 for each food.
IODINE TEST FOR COMPLEX SUGARS (STARCHES
1. Place 5 DROPS of iodine (red solution) on to your food sample.
If the solution turns purplish-black color you have complex sugars (starch).
Record and repeat for each food.

1. Use lactase break lactose down into galactose and glucose
2. Investigate the specificity of lactase
3. Observe what happens if the shape of lactase is changed (denatured) due to heating
4. Include a diagram of the induced fit model.
Materials For Each Group:
5- test tubes
1 - test tube rack
• Introduction:
• Lactose, the sugar found in milk, is a disaccharide
composed of glucose and galactose (both sixsided sugars). Sucrose, ordinary table sugar, is also a
disaccharide composed of fructose and glucose.
Glucose is a six-sided sugar and fructose is a fivesided sugar.
• Lactase is an enzyme that breaks lactose down into
galactose and glucose. Lactase can be purchased
in pill form by people who are lactose intolerant.
These people lack the enzyme, lactase, and
cannot break down the sugar lactose into its
component parts.
• In this lab, you will:
Warm up Sept 25
SWBAT make connections between chemistry and
biology
• What were we testing for in the lab yesterday?

• As a team –
• Re-read your questions you came up with Tuesday.

• Take turns reading the lactose info sheet.
• Answer any questions you still have on left side of
sheet
