Building Monomers of Macromolecules
Introduction:
The term macromolecule by definition implies "large molecule". In the context of
biochemistry, the term may be applied to the four large molecules that make up organisms --nucleic acids, proteins, carbohydrates, and lipids. Macromolecules are made of smaller
subunits called monomers.
REMEMBER: Molecules are 3-D!
Task:
Examine each macromolecule structure and answer the questions that follow.
Glucose
1. Number each carbon in the picture to the right.
2. What is the chemical formula for glucose?
__________________
3. Glucose is a monomer for what macromolecule?
___________________________
4. What other simple sugar(s) has the same chemical formula as
glucose? ________________
5. Simple sugars like glucose are called
____________________________________.
6. What is the function of carbohydrates for the body?
___________________________
Glycine.
7. Place a BOX around the amino group on this picture.
8. Circle the carboxyl group on this picture.
9. Glycine is what type of monomer? _____________________
10. Name the 4 things attached to the center carbon in ALL amino
acids. ______________________, __________________,
