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)

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
