Question

1. summarize: now create a balanced equation for that shows the entire hydrolysis reaction. (in other words, the equation should show how the oligosaccharide broke up into three separate glucose molecules.)

turn on show current formula/equation to check your answer.

1. compare: how do hydrolysis reactions compare to dehydration synthesis reactions?
2. apply: amylose is a carbohydrate that consists of a single chain of hundreds of glucose molecules. consider an amylose molecule with only four glucose molecules.

a. how many water molecules are released when the 4 - glucose amylose forms?
b. what do you think is the chemical formula for this amylose?

Explanation:

Step1: Write hydrolysis equation

An oligosaccharide with three glucose - units hydrolyzes with water. The general formula for glucose is $C_6H_{12}O_6$. The balanced hydrolysis equation for an oligosaccharide (a trisaccharide in this case) breaking into three glucose molecules is $C_{18}H_{32}O_{16}+2H_2O
ightarrow3C_6H_{12}O_6$.

Step2: Compare hydrolysis and dehydration synthesis

Hydrolysis reactions use water to break down polymers into monomers. Dehydration synthesis reactions remove water to build polymers from monomers. They are opposite processes.

Step3: Calculate water molecules in amylase formation

When n monomers form a polymer, the number of water molecules released is n - 1. For an amylase with 4 glucose molecules (n = 4), the number of water molecules released is 3.

Step4: Determine amylase chemical formula

The formula of glucose is $C_6H_{12}O_6$. When 4 glucose molecules form amylase with the release of 3 water molecules ($3H_2O$), the formula of the 4 - glucose amylase is $C_{24}H_{42}O_{21}$.

Answer:

1. $C_{18}H_{32}O_{16}+2H_2O

ightarrow3C_6H_{12}O_6$

1. Hydrolysis uses water to break polymers; dehydration synthesis removes water to build polymers. They are opposite processes.
2. A. 3

B. $C_{24}H_{42}O_{21}$
