Monosaccharides (Glucose) What color is Benedicts before testing? What is it used to test the presence of? glucose
Which tests are positive for glucose? Which sample shows the highest amount of glucose?
Which is a positive test for glucose? What do the various colors mean?
Iodine is what color at start? Which test tube below is a positive test? Which is the control? Left is potato starch Right is distilled water
Which test positive for starch? Look for blue-black color
Would you say the iodine and potato (left) is a positive or negative test? Would you say the iodine and onion (right) is a positive or negative test?
How do glucose molecules and starch molecules compare? glucose starch
Sucrose: glucose + fructose
Sudan IV turns fats red Can you tell where the fat and where the water is in this test tube?
Sudan IV and Milk
What are some difficulties of testing beef broth? Why did we change to chicken broth?
Is this a positive or negative fat test? Before After drying Positive

Would this cat make a positive fat test?
What color is Biurets at start? How do you know if your sample is positive for protein?
PROTEIN TEST Table 5
Does milk have protein? Added Biurets
SUMMARY OF MACROMOLECULE LAB TESTS
HONORS BIOLOGY Testing Macromolecules. Qualitative Detecting if a substance is present You won’t be determining how much.
Biology Ms. Haut. 1. Add 1 ml (10 drops) of Benedict’s solution to the test tube. 2. Add 8 drops of sample solution to a test tube. 3. Heat the mixture.

Test for simple (reducing) sugars Benedict’s is blue Put test substance in a test tube with distilled water and a few drops of Benedict’s Heat.
In this lab, you will 1. Learn the names of specific indicators 2. Learn the what a specific indicator test for 3. Be introduced to three organic compounds,
Organic Molecules Pre-Lab: Reagents 1. What is a reagent? 2. What simple sugars does Benedict’s Reagent test for? 3. How can Benedict’s reagent be used.
Organic Compounds Lab Procedure. General Directions for all Tests 1. Before beginning, make predictions for all tests. 2. Label the test tubes 1-7 Note.
