2. Elements of Life 96% of living organisms are made of: carbon (C)
oxygen (O)
hydrogen (H)
nitrogen (N)

3. Types of Compounds Organic  Both C and H present
 Living or once living
Inorganic
 Do not contain both C and H
 Non-living

4. Organic or Inorganic? Organic Organic H2O: CO2: C6H12O6: C12H22O11:
NaCl:
Inorganic

5. Molecules of Life What are bodies made of?
Put C, H, O, N together in different ways to build living organisms
What are bodies made of?
Carbohydrates
sugars & starches
Proteins
Fats (lipids)
nucleic acids
DNA, RNA

6. Carbohydrates

7. Carbohydrates Source of ENERGY Building block molecules = sugars
sugar - sugar - sugar - sugar - sugar
sugar

8. Sugars = building blocks
Names for sugars usually end in
glucose
fructose
sucrose
maltose
-ose
fructose
maltose
Sucrose

9. Structure of Glucose C_ H_ O_ Glucose 6 12 6 6 12 6 Carbon__________

10. Carbs continued One sugar= Monosaccharide
Two sugars connected= Disaccharide
Many sugars connected in a long chain= Polysaccharide

11. Building Carbohydrates
Synthesis
1 sugar = monosaccharide
2 sugars = disaccharide |
glucose |
glucose |
maltose

12. Monomer:
Polymer:

13. Examples of Carbohydrates
A. 1 Sugar = Monosaccharide/Simple Sugar
Ex: Glucose & Fructose
(C6H12O6)
B. 2 Sugars = Disaccharide
Ex: Maltose, Sucrose, Lactose
(C12H22O11)
C. Many Sugars = Polysaccharide
Ex: Starch, Glycogen, Cellulose
