Macromolecule Webquest
The next chapter we will be learning about 4 different organic compounds found in our bodies called
“Macromolecules”. These compounds include carbohydrates, lipids, proteins, and nucleic acids. Today we will be
using a variety of resources to learn about each of the four organic compounds. Follow the directions carefully to
make sure that you complete each step of the webquest. If you have a question or a problem with the
computer/website, please ask for help!!
A) CARBOHYDRATES - Go to the following website and read about carbohydrates and answer the questions
that follow: http://goo.gl/hiClX9
1. What are the building blocks (monomers) of carbohydrates?
2. What is the main purpose of carbohydrates in our bodies?
3. What types of food can we eat to obtain carbohydrates?
4. What are the 3 types of carbohydrates? Explain each one and give an example of food you can eat that
contains each type:
B) LIPIDS
Part 1 – Go to the following website to read about lipids and answer the questions that follow:
