Topic: Biomolecules of life
• EQ: What are the 4 biomolecules? What is the
structure and function for carbohydrates and
lipids?
Organic Molecules
You just need a processing page.
What do you think of when you think
of building blocks?
Examples of building blocks
•
•
•
•
Many slices of bread = 1 loaf of bread
Many bricks = 1 brick wall
Many beads = 1 bead bracelet
Many links = 1 chain
What are organic molecules made of?
• Molecules containing
carbon.
• They also often
contain hydrogen,
oxygen, and nitrogen.
What are the 4 types of organic
molecules?
1.
2.
3.
4.
Carbohydrates
Lipids
Proteins
Nucleic Acids
What is the difference between a
monomer and a polymer?
• A monomer is ONE subunit (building block) of an
organic molecule.
• A polymer is MANY monomers put together.
Carbohydrates
Monomer:
• monosaccharide
Examples:
• Glucose
• Galactose
• Fructose
Carbohydrates
Polymer:
• polysaccharide
Examples:
• Starch (in plants)
• Cellulose (in plants)
• Glycogen (in animal)
Processing Piece:
• Draw a hexagon and label it glucose. Then draw a
chain of glucose molecules and label it “starch”.
molecule.
• Label one picture “monosaccharide” and the other
“polysaccharide.”
• Answer this question: What molecules would you
get if you broke down a starch molecule?
Carbohydrates
• Function:
–Monosaccharides = quick energy.
Mitochondria use monosaccharides like
glucose to make ATP.
–Polysaccharides = stored energy.
Polysaccharides like starch can be broken
down QUICKLY into monosaccharides when
your body needs energy.
Carbohydrates
• Composition:
– Carbon, oxygen, and hydrogen (Circle these
on your paper.
Lipids
Monomer:
• Fatty acids and glycerol
Polymer:
• Lipids
Lipids
• Function:
– Long-term energy storage.
–Insulation in animals; conserving heat and
keeping you warm.
Processing Piece:
• Write “carbohydrate” and draw a picture to help
you remember its function. (Example: You could
draw an energy drink, or candy, or a person with a
lot of energy.)
• Write “lipid - insulation” and draw a picture to help
you remember its function. (Example: You could
draw a picture of a coat or a blanket or a fire to help
you remember that lipids help you conserve heat
and stay warm.)
Lipids
• Composition:
– Carbon, oxygen, and hydrogen (Circle these
on your paper.)

Assign Yourself: Parent signature and
commentary. Pg 166-171 (BOOK)
stickie/annotate and outline (due tmw)
• DO NOW:
• Collins Writing Type 2, 5 – 8 lines
• Compare and contrast carbohydrates and lipids’
structure and function. You must include the
following terms: composition, monomer, polymer,
monosaccharide, polysaccharide, fatty acid, lipid,
function. Underline the words when you use
them.
Topic: Biomolecules
• EQ: What is the structure and function of
proteins and nucleic acids?
Proteins
Monomer:
• Amino acids
Polymer:
• Polypeptide
Processing Piece:
• Draw a circle and label it “amino acid”. Then draw
a chain of amino acids and label it “polypeptide”.
molecule.
• Label one picture “monomer” and the other
“polymer.”
• Answer this question: What molecules would you
get if you broke down a protein molecule?
Proteins
• Function:
–Many different jobs.
Examples: Storage, transport, cell-to-cell
communication, growth and repair, structural
support, and much, much more.
What are enzymes?
• Special proteins that catalyze (speed up)
reactions in your body.
Proteins
• Composition:
– Carbon, oxygen, hydrogen, and nitrogen
(Circle these on your paper.)
Nucleic Acids
Monomer:
• Nucleotides
Polymer:
• Nucleic Acid
Processing Piece:
• Draw a triangle and label it “nucleotide”. Then
draw a chain of nucleotides and label it “nucleic
acid”.
• Label one picture “monomer” and the other
“polymer.”
• Answer this question: What molecules would you
get if you broke down a DNA molecule?
Nucleic Acids
Function:
• Stores hereditary information (your genes).
• Controls the production of proteins.
Nucleic acids
• Composition:
– Carbon, oxygen, hydrogen, and nitrogen
(Circle these on your paper.)

Processing Piece:
• Write the word “enzyme” and draw a picture
to help yourself remember the definition.
