- Life can't exist without carbon
- Carbon produces carbon skeletons & functional groups
- Organic & inorganic molecules
- Organic has carbon inorganic does not
- carbon bonds with many elements eg. carbon & hydrogen = hydrocarbons
- Carbon skeletons attach to functional groups
- Monomers & polymers produce bio molecules
- all living cells have thousands of polymers
- Large molecules: lipids, carbohydrates, proteins, nucleic acid
- Building & breaking polymers- Dehydration reaction
- Dehydration reaction is: a monomer is added to a chain and a water molecule is released
- Breaking down- break by adding water
Concept check:
- C3H8O
- Explain the connection between monomers and polymers. Polymers are made of monomers
- What molecule is released during construction of a polymer? What is this reaction called? A water molecule is released during the construction of a polymer it is the dehydration reaction
- Draw three ways 5 carbon atoms could be joined to make different carbon skeletons.
