Your notebook Pen/pencil Chromebook (optional, only if you can’t see the screen) Ruler (only if you didn’t finish notebook setup yesterday) Biomolecules Carbs Notes page RED light for phones today – either put away or in phone slots on wall You have 5 MINUTES to finish notebook setup from yesterday. PPT is on Moodle. YOU NEED:
3
Write BIOMOLECULES CARBS NOTES 8-31-17 at the top of the page
Write BIOMOLECULES CARBS NOTES at the top of the page. Take notes on the half sheet and AFTER YOU’VE FINISHED, glue paper into notebook. Underneath the notes, write CLOSING and then answer the last question in a complete sentence.

Put the following in order from what you think is smallest to largest.
Think About: Put the following in order from what you think is smallest to largest. MONOMER, molecule ATOM CELL ORGANELLE TISSUE POLYMER, molecule ORGAN 4

Two or more atoms bonded together Carbohydrates (sugars)
Biomolecules Two or more atoms bonded together Life Biomolecules are large molecules that make up living things. Proteins Carbohydrates (sugars) Nucleic Acids Lipids (fats)

Biomolecule: Carbohydrates A carbohydrate is a biomolecule that supplies us with energy and has a 1:2:1 ratio of Carbon:Hydrogen:Oxygen in the molecule. The subunits (monomers) of carbohydrates are single sugars, called monosaccharides. 6.3 Section Summary 6.3 – pages
7
Biomolecule: Carbohydrates
Carbs range from small sugar molecules to long starch molecules we consume in pasta and potatoes. Key source of energy found in most foods — especially fruits, vegetables, and grains
8
Carbohydrates: Monosaccharide: single sugar unit
Examples: Glucose (C6H12O6) Fructose (Fruit Sugar) Galactose glucose
9
GLUCOSE Glucose is the simple sugar (monosaccharide) that plants make during photosynthesis. Plants use glucose: As an energy reserve until they need it To grow taller and bigger To create products such as plant hormone. Animals use glucose: As an energy reserve until we need it For energy It is known as our “blood sugar”
10
Biomolecule: Carbohydrates
MONOSACCHARIDES Simple sugars glucose, fructose, and galactose have the same formula: But they are different because the atoms are arranged differently:
11
Carbohydrates Disaccharide: double sugar unit Examples:
Sucrose (glucose+fructose) Lactose (glucose+galactose) Maltose (glucose+glucose) glucose Sucrose – cane sugar Lactose – milk sugar Maltose -
12
Polysaccharides Many sugars (basically a large molecule made of lots of single sugars bonded together) Examples: starch (glucose storage in plants) glycogen (glucose storage in animals) cellulose (fiber, plant cell walls) chitin (insect exoskeleton, fungus cell walls) glucose cellulose
13
CLOSING In your notebook on pg 12 under the notes, answer the following questions Why do athletes “carb-load” before an event? 2. The simple sugar glucose has a chemical formula of C6H12O6 Table sugar, known as sucrose, has a chemical formula of C11H22O11 Using this information, what mathematical statement would describe the ratio of elements found in carbohydrates?
