Objective: IWBAT analyze carbon-

based molecules to investigate the

different kinds of macromolecules.

Day 1:

Macromolecules

CARBONCARBON

MacromoleculesMacromolecules

• Carbon atoms can be joined together Carbon atoms can be joined together to form many different carbon to form many different carbon moleculesmolecules

• Large compounds formed by joining Large compounds formed by joining many smaller molecules together are many smaller molecules together are called called macromoleculesmacromolecules

Four important Four important macromoleculesmacromolecules

• CarbohydratesCarbohydrates

• LipidsLipids

• ProteinsProteins

• Nucleic acidsNucleic acids

• In carbon-based molecules, small In carbon-based molecules, small molecules make a long chainmolecules make a long chain– MonoMonomer: Each small part of a mer: Each small part of a

complete moleculecomplete molecule

– PolyPolymer: A large molecule, or mer: A large molecule, or macromolecule, made of many macromolecule, made of many monomers connected togethermonomers connected together

Bottom lineBottom line

All macromolecules (polymers) All macromolecules (polymers) are synthesized (made) from are synthesized (made) from simple precursors (monomers)simple precursors (monomers)
