+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)
