+Today Thursday
9/17/15 You will…1. Complete ISN pg.23
You will need: 1. ISN2. Something to write with 3. Two blue sheets from up
front
Bell work: Glue in and read• Vote for me – Biomolecule of the Year –ISN pg 24• Poster Rubric – ISN 25
2. Start working on
macromolecule poster
+
Did you know?
Mantis Shrimp can make a noise loud enough to break glass
+ WHAT are MacroMolecules???Molecules made of Carbon = Organic
Make up all living thingsThey are large (macro)There are 4 of them:
1. Carbohydrates2. Lipids3. Proteins4. Nucleic Acids
They are composed of varying amounts of C, H, O, N
+3 Shapes of Carbon
1. Straight chains
2. Branched chains
3. Rings
+CARBOHYDRATES•Food examples:
• Sugars & Starches:• Potatoes, grains,
breads, pasta• Simple sugars
•Functions :• Chemical energy! Short
term• Plants Forms cell walls
& supports plants• Cell-to-cell
communication
Carbohydrates- Hexagon
- End in -ose
p.45 in Text
MOLECULAR STRUCTURE!
+ LIPIDSFood examples:•fats, oils, cholesterol
• FYI: Cholesterol good –regulates response to stress; testosterone, estrogen
Functions :
• Store long term energy for cells
• Makes up Cell Membrane
Lipids- LONG Chains w/ tails
p. 46 in Text, bottom
Unsaturated = at least ONE C=C double bond
MOLECULAR STRUCTURE!
+
PROTEINS•
•Food examples:• Steak, egg, cheese
•Functions:• Structure• Movement, eyesight, digestion
• Carries oxygen• Build & repair tissues• Fight infection• Form enzymes
Proteins- Look for word Amino Acid, R-Group,
or Carboxyle- End in –ase
p.47 in Text
MOLECULAR STRUCTURE!
C = O
+
NUCLEIC ACIDS DNA & RNA
Function:• Store & transmit
genetic information
• Make proteins!
Two types• DNA = DeoxyriboNucleic
Acid • RNA = RiboNucleic Acids
Nucleic Acids- Double Helix
- Includes Sugar, Phosphate, N Base
p.230 in Text
MOLECULAR STRUCTURE!
+
BUILDING BLOCKS!
+ MONOmer vs POLYmer
+BUILDING BLOCKS!
ALL 4 MACRO-MOLECULES are made up of C, H, O, N
1.Carbohydrates – saccharides
2.Lipids – Fatty Acids (Saturated – from animals, Unsaturated – from plants)
3.Proteins – Amino Acids
4.Nucleic Acids – Nucleotides
+Election Poster
Which macromolecule is the best?
+Wendy Water
A well balanced molecule with both positive and negative sides
Helps you keep your cool by maintaining Homeostasis
Filling each and every cell in your body
Wendy is made up of 2 Hydrogen and 1 oxygen
H 2O
If you aren’t voting Wendy
Water you thinking!!
+Election Poster must include…
Name of Macromolecule
Elements found in your molecule
Your elements monomers/subunits
What food it’s found in
Function in the cell
Chemical Structure
What makes it the molecule that it is
Why is it so special (catch the audience)
