Carbon is the main ingredient of organic molecules Ch. 5.1

Carbon Skeletons and Functional Groups Carbon is found in ___________________ Can _______________________________ Can ____________________with other atoms When bonding with other atoms, forms a ______________________________ ____________________________  any __________________ molecule Molecules without carbon are called __________________________ Ex. _____________

Carbon Skeletons

Organic molecules of _____________ and _______________  ________________ Ex: fuels like methane (______________)

________________________  group of atoms in a molecule that act in ___________ ways with _________________________ Need to know the structures! The ____________________________ group determine the ________________ of organic molecules Ex. ___________________  water-______ (attracted to H 2 O) and ________________ → water-____________ (repelled by H 2 O)

Functional group diagrams

Monomers and Polymers _____________ are small molecular units

Chain of monomers  _______________

When a monomer is _______________; ____________________________is _____________________ (_______________ REACTION) When a monomer is __________________; ___________________________________ (__________________ REACTION) “hydro” = ______________ “lysis” = ________________

4 main categories for large molecules Every living cell has thousands of different kinds of ________________ Life’s large molecules: ______________________

Concept Check 1. Draw a molecule that has a 3-C skeleton and a hydroxyl group in the middle carbon 2. Explain the connection between monomers and polymers
