You get to answer this question at the end!

2. Carbohydrates are organic compounds
Carbohydrates are organic compounds.We know them as sugars and starches.
Organic compounds have carbon in them.
Carbohydrates are made of carbon, hydrogen, and oxygen usually in a 1:2:1 ratio.
CHO

3. Use the following to make the formula for glucose sugar C 6 H__ O__ don’t for get the 1:2:1 ratio

4. Use the following to make the formula for glucose sugar C6 H_12_ O_6_ don’t for get the 1:2:1 ratio

5. The subunits or monomers that make up carbohydrates are simple sugars or monosaccharides

6. The monomers of carbohydrates are monosaccharides.
3 examples of monosaccharides (also known as sugars).
Glucose : in blood or leaves
Galactose : from milk
Fructose :in fruit

7. The polymer of a carbohydrate is called a
Polysaccharide.
Many monosaccharides make a polysaccharide.
Monosaccharide
Polysaccharide

8. Carbohydrate Polysaccharides- 4 types
1.Plant starch
Stores energy for future use. Example: potatoes & carrots
=Storage Starch
2.Cellulose
Makes up cell walls in plants. Gives strength and rigidity as well as flexibility to plants.Celery is a good example of a vegetable with lots of cellulose.
=Structural Starch

9. Complex carbohydrates continued…
3. Glycogen – animal starch
Stored in liver and muscles to provide energy and regulate blood sugar levels.
=_______________4. Chitin – exoskeletons of insects
=_______________

10. Goggles On
Use an eye dropper to drop 1 – 2 drops
of Lugio’s Iodine indicator solution
onto each of the six samples in the
white dish at your lab station.
do not touch the samples with the dropper
What do you think the results mean?
Leave you dishes I will clean up.
Go back to your seat and write notes.

11. Indicator solutions test to see if a specific
substance is present.
Benedict’s solution can be used to test for
monosaccharides (sugars) Blue for neg.
yellowish for positive.
Iodine can be use to test for polysaccharides

12. Foods that have lots of carbohydrates fall into 2 categories
Simple carbohydrates
Sugary foods
Highly processed grains – white bread, white rice, & pasta
Gives you that SUGAR RUSH
Complex carbohydrates
Whole grain foods, fruits and vegetables
These are broken down slower in the body and are better for you

13. Complex carbohydrates are made of many sugar molecules.
The fiber in whole grain slows the transformation from starch to sugar.

14. Carbohydrates give you energy!
So choose heart healthy whole grain carbohydrates fruits and vegetables

15. What might happen without enough carbohydrates?
Something really really sad!

16. Fall asleep in Science Class???????

_C_ __ __ __ __
Plants use photosynthesis to make monomers of carbohydrates known as sugar, or monosaccharides.
When other elements from the soil (nitrogen, phosphates, and sulfur are added plants can make all the organic
macromolecules we have been studying.
These macromolecules are then passed through the food chain. Polymers are digested into monomers to make
polymers for the organism that ate the food.

18. Science Standard ALL STUDENTS WILL GAIN AN UNDERSTANDING OF THE STRUCTURE, CHARACTERISTICS, AND BASIC NEEDS OF ORGANISMS AND WILL INVESTIGATE THE DIVERSITY OF LIFE.
