Student Exploration: Dehydration Synthesis
Vocabulary: carbohydrate, chemical formula, dehydration synthesis, disaccharide, glucose,
hydrolysis, monosaccharide, polysaccharide, valence
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. If you exercise on a hot day, you need to worry about dehydration. In this context, what do
you think dehydration means? Dehydration is the loss or removal of water from your body.

2. Astronauts and backpackers often bring dehydrated food. What do you think dehydrated
co

What do rice, potatoes, and sugar have in common?
They are all foods rich in carbohydrates. Carbohydrates
aC s
are an important energy source for your body. The basic
vi y re
building block of most carbohydrate compounds is the
molecule glucose. Using the Dehydration Synthesis
Gizmo™, you will learn about the structure of a glucose
molecule and how glucose molecules can be joined
ed d
together to make larger carbohydrate molecules.

To begin, select the CREATE GLUCOSE tab.
1. Look at the chemical formula for glucose. How many carbon (C), hydrogen (H), and
is
oxygen (O) atoms are found in a molecule of glucose? C:____6___ H:__12_____
Th
O:___6____
sh
2. Turn on Show chemical structure. Each black sphere represents a carbon, hydrogen,
or oxygen atom. The lines connecting the spheres represent chemical bonds.
A. How many black spheres are in the diagram? ____24___

, B. How does this relate to the number of carbon, hydrogen, and oxygen atoms in the
chemical formula for glucose? • In the chemical formula there is a total pf 24 atoms
that are a mix of carbon, hydrogen and oxygen. When you count the black spheres
there is also a total of 24.
