PART1: BUILDING A MACROMOLECULE: All living things make large molecules, called
macromolecules, from smaller molecules. Macromolecules can be made from a few repeating units, or
can be composed of hundreds or thousands of smaller molecules. Each macromolecule has properties
quite different from the units of which is composed. Study the diagrams below, which show
carbohydrate molecules. Beside Each molecule, write whether it is a monosaccharide, a
disaccharide, or a polysaccharide.

PART 2: DEGREE OF SATURATION (Lipids): Each of the following structural formulas shows a fatty
acid molecule. On the line, identify the fatty acid as saturated, unsaturated, or polyunsaturated.
1.
Define a saturated fatty acid. Provide one example of a saturated fatty acid.
2. Define an unsaturated fatty acid. Provide one example of an unsaturated fatty acid.
3. Define a polyunsaturated fatty acid.

What evidence is there of this process? ____________________________________
PART 4: DEHYDRATION & HYDROLYSIS: Below is an example of dehydration synthesis. In
dehydration synthesis, a hydrogen atom from one molecules joins a hydroxyl group (-OH) from another
molecule to form water, leaving two molecules bonded to the same oxygen atom. For example, when
glucose and glucose combine by dehydration synthesis, they form maltose and water.
Below is an example of hydrolysis. Complex organic molecules are broken down by the addition of the
components of water –H+ and –OH-.
1.
What are the products of the hydrolysis reaction?__________________________
2. What are the reactants of the dehydration synthesis reaction? ________________________
3. How are the reactions in #1 & #2 related?__________________________________________

4. Look at the three reactions below. Which reaction(s) is/are hydrolysis taking place? __________
How do you know? _____________________________________________________
5. Look at the same three reactions. Which reaction(s) is/are dehydration synthesis taking place?
________ How do you know? __________________________________________________
