3. LESSON OBJECTIVES:
1. summarize the general characteristics of
each biomolecule;
2. cite sources of each macromolecule;
3. realize the importance of biological
molecules in our body.
4. simplest form of
carbohydrates
Definition of Terms
Monosaccharide
Monomer
a molecule that can react
with other molecule to
form very large molecules
or polymers
Peptide
short chain of amino
acid monomer link
by peptide bonds
5. Hormones
special chemical
messengers that are
created in the endocrine
gland
Amino acids
organic compounds that
combined to form
proteins
Enzymes
proteins which make the
bio chemical reaction
fast
Phospholipids
contain glycerol, two-fatty
acids, and a phosphate
group
6. Nucleotide
made up of three components: nitrogen-
containing base, five-carbon sugar, and a
phosphate group
7. Macromolecule Plates and Glass
1. Write inside the first plate an example of food rich
in carbohydrates that you have eaten a while ago
and tell us what you feel after eating it.
● What did you feel after eating the food rich in
carbohydrates?
2. Write inside the second plate an example of food
rich in lipids that you have eaten a while ago.
● What did you feel after eating the food rich in
lipids?
8. What
macromolecules do
you think is needed
by animals that
hibernate for long
periods of time?
Would you consider
aandy bar as the
main source of long
term energy? Why?
What type of
macromolecule is found
in every ingredient of
the macaroni soup?
9. Biological Macromolecules
Carbohydrates
Main source of energy
Ex. Rice, cereal,
potatoes
Proteins
Help build tissues and
help in body
processes
e. meat, fish, nuts
Lipids and Fats
Long –term storage of
energy in the body
Ex. Fats and oils
Nucleic acids
Involves the genetic
materials, the
blueprint of life
Ex. RNA and DNA
12. Disorders

Macromol
ecules
Function of Macromolecules
Diabetes
Mellitus
Carbohydrat
e
Carbohydrate becomes sugar when
break down which gives energy.
Increased carbohydrate intake causes
elevated blood
sugar.
Kwashiorko
r
Protein Protein is essential in building muscle
mass. Decreased intake of protein can
lead to
Kwashiorkor.
Myocardial
Infarction
Lipid Lipids or Fats maintain body
temperature. Too much lipids or fats
in the body narrow blood vessels
which decreases blood
flow.
13. Assignment
Study the molecular structure of each molecule.
What are the elements present in each molecule
Answer in notebook.
Emphasize the structural hierarchy from monomer to polymer to cellulose to a grouping of cellulose into a microfibril to the structure of the cell wall to the plant cell to the leaf. Whew!
