Transcript of Macromolecules, Day 3
LaunchLaunchWrite the monomer and polymer names for Write the monomer and polymer names for
the four types of macromoleculesthe four types of macromolecules
MacromoleculesMacromoleculesDay 3Day 3
Carbohydrates
Made of carbon, hydrogen, and oxygen
Used as main energy source for living things
Sometimes used as structural support
Plant walls and exoskeleton
Building carbohydrates
Carbohydrates= forms of sugars
Carbohydrates have the ability to store the most amount of energy per gram out of all the macromolecules
Structure of a Carbohydrate
What do you notice about this structure?
Rings connect to form
polysaccharides (polymer /
macromolecule)
Lipids
Examples:Fats, waxes, oils
Made mostly of carbon and hydrogen
Used to store energy
Hydrophobic=scared of water
Building lipidsMade of 3 fatty acids attached to glycerol
Different types of fats
Saturated fats (ex. butter)
Unsaturated fats (ex. oil)
Gly

ProteinsSome help chemical reactions happen faster (enzymes)
Some help support cell structure
can also be used for energy
Proteins
Made from DNA and RNA
Order of monomers is extremely important
Building proteinsMade up of amino acids
Different order of amino acids = different proteinsMust be folded correctly to work

Nucleic AcidsStores and passes along genetic material
2 types: DNA and RNA
Made of strands of nucleotides, which have a base made of nitrogen
Order of monomers is extremely important
Building nucleic acids
The building blocks of nucleic
acids are nucleotides
