“IN”
•What did you eat for
breakfast?
• What are the important
substances in the food?
Why?
Objective:
By creating a concept map
and completing a lab
activity, I will be able to
compare the structures and
functions of different types
of biomolecules.
• What do they do for our
bodies?
“OUT”
Message Board:
•Projects due tomorrow!!
•Quiz tomorrow!!!
•Turn in all missing work!

What we will do today
 Concept Map of Biomolecules
 Biomolecule Lab (ON TABLE!)
Carbohydrates, Proteins, Lipids,
Nucleic Acids
Here we go… 
Carbohydrates
 Macromolecules:
– Starch
– Glycogen (animal starch)
– Cellulose (fiber)
 Subunit:
– Glucose
– (fructose & galactose are other monosaccharide
simple sugars)
Disaccharides (double sugars)
 Maltose – in grains (glucose, glucose)
 Lactose – in milk (glucose, galactose)
 Sucrose – table sugar (glucose, fructose)
Extra slide – not mandatory
according to CSCOPE
Carbohydrates
 Good for:
– Providing energy
– Composition of cell wall
– Providing structural support
Lipids
 Macromolecules:
– Fats and phospholipids (play in “phospho” as
phosphorus…abundant element from Tuesday)
 Subunit:
– Glycerol, fatty acids and phosphate groups
 Good for:
– Long term energy storage
– Insulation
– Protective covering (cell membrane)
Proteins
 Composed of C,H,O,N
 Macromolecules
– Globular protein
– Structural protein
 Subunit
– Amino acid
Proteins con’d
 Good for:
– Used as building blocks
– Enzymes (Act as catalysts to speed up chemical
reactions)
Nucleic Acids
 Macromolecules:
– DNA & RNA
 Subunits:
– Nucleotides (sugar, phosphate, nitrogen base)
 Good for:
– Storing information
– Gene encoding
– Gene expression

Are your favorite foods
made mostly of
carbohydrates, proteins,
or lipids? Are they good
for you?
