What is hydrolysis?
It is a chemical process breaking down
polymers
.
What is the key molecule removed in hydrolysis?
Water
What are the main components of a hydrolysis reaction?
Water: Provides
hydrogen
and hydroxyl groups
Polymer
: Large molecule being broken down
Monomer
: Smaller units resulting from breakdown
Enzyme
: Catalyzes and speeds up the reaction
What are the names of the four molecules shown in the image?
Maltose
Water
Glucose
Glucose
What are the two reactants (R1 and R2) that undergo co-polymerization?
R1 = -
OH
R2 =
Ph
or -O
How does mechanical force affect copolymerization?
It allows manipulation of the
polymer chain
What is the chemical reaction that occurs during hydrolysis?
Water (H2O)
is added to break down larger molecules into smaller molecules
This process converts
maltose
into
glucose
What happens during the hydrolysis of maltose?
Water's oxygen joins one glucose subunit
Water's hydrogen joins the other glucose subunit
The
glycosidic bond
is broken
Converts maltose into two glucose
monomers
What is the function of hydrolysis?
It breaks down
polymers
.
How does the structure of glucose differ from the structure of maltose?
Glucose has a
6-membered
ring structure
Maltose has two 6-membered ring structures connected by an
oxygen
atom
What are the three processes involved in polymer hydrolysis reactions?
Polymer Formation:
CBI
+
Monomers
→ Linear Polymer
Mechanical Breakdown: Polymer Chain → Shorter Fragments
Hydrolysis: Polymer Chain → Individual Monomers
How does the hydrolysis of starch illustrate the components of a hydrolysis reaction?
Starch and water produce
glucose
through hydrolysis
How does hydrolysis break polymers?
By adding a
water molecule
across the bond
How does the hydrolysis of maltose differ from the hydrolysis of glucose?
Maltose is
broken
down into two glucose molecules, while glucose is not further broken down
What is the chemical formula for maltose?
C

What is the function of condensation?
It forms
polymers
.
What role does the oxygen atom of water play in hydrolysis?
It attacks the
glycosidic bond
What is the result of hydrolyzing maltose?
Two
glucose
monomers
What role does water play in a hydrolysis reaction?
Provides
hydrogen
and
hydroxyl
groups
What is the purpose of the co-polymerization process shown in the image?
To create a new polymer compound from the
CBI
and
R2
reactants
What is the role of the mechanical force shown in the image?
To induce the
co-polymerization
process between the
CBI
and
R2
reactants
What happens during the mechanical breakdown of a polymer chain?
It
produces
shorter
fragments
What is the main reaction type described in the material?
Hydrolysis
How does hydrolysis break down large molecules?
By adding
water
to the molecules.
What role does copolymerization play in polymer chains?
It creates a chain that can be manipulated
What is the result of hydrolysis on a polymer chain?
Individual
monomers
are produced
What process breaks down polymers into monomers?
Hydrolysis
How does the co-polymerization process differ from the hydrolysis process shown in the image?
Co-polymerization creates a new polymer
compound
, while hydrolysis breaks down the polymer
What is the process of polymer formation from CBI and monomers?
Linear Polymer
What is the purpose of the hydrolysis process shown in the image?
To break down the
co-polymer
compound into further transformations
What are the smaller building blocks resulting from hydrolysis called?
Monomers
What is the name of the chemical compound shown on the left side of the image?
CBI
What is the purpose of hydrolysis in the context of polymers?
To break down polymers into individual
building blocks
What is the name of the process shown in the image?
Hydrolysis
What is the key molecule added in hydrolysis?
Water
What is the comparison between hydrolysis and condensation?
Hydrolysis:
Breaks down
polymers
Adds water
Removes water
Condensation:
Forms polymers
Adds water
Removes water
In the hydrolysis of starch, what is the product formed?
Glucose
What is the role of an enzyme in a hydrolysis reaction?
Catalyzes
the reaction and speeds it up
