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)

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
