3. Describe the relationship between monomers and polymers
4. Explain the difference in dehydration and hydrolysis
What Makes Something Organic?
 Containing Carbon
Objective 1: Explain the bonding
properties of Carbon
 Carbon has 4 valence e It can form 4 covalent bonds with up to 4 different
elements at a time
 These are usually C, H, O or N
 In life, these carbon bonds make up the 4 Major
Macromolecules of life…biochemistry
Biochemistry
Objective 2: Explain what a macromolecule is and how it is formed
Objective 3: describe the relationship b/t monomers and polymers
 There are 4 organic macromolecules
 Macromolecule—really large molecule made up of
smaller molecules
 A.k.a—polymer
 Polymers are made up of monomers
 Monomers link together to make polymers
Objective 4: explain how dehydration and hydrolysis differ
How are Macromolecules Made???
 Dehydration Synthesis
 Dehydration=taking away water
 Condensation reaction
Dehydration Synthesis
How are Macromolecules Broken?
 If you take away water to make a macromolecule…
 You add water to break them!
 Hydrolysis
