Chapter 5
The Structure and
Function of
Macromolecules
Focus on:
Elements
in each molecule
How molecules are linked
and unlinked
Examples and functions of
each type of molecule
Macromolecules
Monomer
Condensation Synthesis
or Dehydration Synthesis
Hydrolysis
Four Main Types Of
Macromolecules
For each Macromolecule
know the following:
Elements
it contains
Monomer units and
structures
Examples
Uses or roles
Carbohydrates
Types Of
Carbohydrates
Monosaccharides
Monosaccharides
Examples
- OSE
Word
ending common for
many carbohydrates.
Disaccharides
Examples
Oligosaccharides
Polysaccharides
a glucose and b glucose
Starch
a glucose
Cellulose
b glucose

Triacylglycerols
Saturated Fats
Unsaturated Fats
Question
Why
do fats usually contain
saturated fatty acids and oils
usually contain unsaturated fatty
acids?
Fats
Question ?
Which
has more energy, a kg
of fat or a kg of starch?
Phospholipids

Steroids
Proteins
Uses Of Proteins
Structure
Enzymes

Is Protein Structure
Important?
Denaturing Of A
Protein
Comment
Many
other amino acids are
possible (change the R group)
Whole new group of proteins
with new properties can be
made
Genetic engineering can use
bacteria to make these new
proteins
Nucleic Acids
Nucleic Acids
Nitrogenous Bases
Pentose Sugar
Nucleosides and
Nucleotides
DNA
RNA
DNA and RNA
More
will be said about DNA
and RNA in future lessons.
Summary
Role
of hydrolysis and
dehydration synthesis
For each macromolecule, know
the following:
Elements
and monomers
Structures
Functions
