1
Carbon Compounds An introduction to the structure and function of carbon containing molecules
2
Atomic Basis of Life? Can atoms in non-living things like dirt and rocks be the same as atoms in “organic” or living things?
3
What do you think “organic” means?
4
Science definition Carbon containing molecule
5
Properties of Carbon Tetravalent Forms covalent bonds Can form double and triple bonds Can form chains and rings
6
Which molecules are organic? NaCl C C 6 H 12 O 6 CO 2 Ne MgCl 2 C2H7O2NC2H7O2N
7
Which other elements are essential to living things? CHONPS Carbon Hydrogen Oxygen Nitrogen Phosphorous Sulfur
8
“Macromolecules” Macromolecule Four Types: Carbohydrates Lipids Proteins Nucleic Acids
9
Graphic Organizer: categorizing macromolcules Structural elements: Elements Structure of Monomers/Polymers Differences in structure lead to: Nutritional Needs Functions in the body
10
Monomers & Polymers Monomer Single Unit Polymer Repeating subunits Glucose
11
How do you make a polymer? Dehydration Synthesis To build polymers Lose a water molecule
12
Dehydration Synthesis of Maltose
13
How do you break down a polymer? Hydrolysis To break down Requires a water molecule
14
Functional Groups: Structures that give properties to a molecule Hydroxyl-OHAlcoholPolar, form H-bonds Carboxyl-COOHOrganic Acids, amino acids Acidic Amino-NH2Amino acidsBasic Sulfhydryl-SHProteinsForm sulfide Bonds Phosphate-PO4DNA, ATPStore energy
15
Find the functional groups! Can sugar dissolve in water? ATP…what might be the function of this molecule?
16
Two more… More than one functional group?!? What gives this molecule its twist?
17
Understanding the Macromolecules Modeling Notes Expert Groups Mixed Groups Macromolecule Lab Worksheet Review
