1. A quick source of energy!!
Carbohydrates
A quick source of energy!!

2. What elements are carbs composed of?
Carbon (C), Hydrogen (H) and Oxygen(O) In a ratio of – C : H : O 1 : 2 : 1 Example: Glucose C6H12O6 6
For every 1 Carbon (C) You will have
2 Hydrogens (H)
and
1 Oxygen (O).

3. Carbohydrate Monomers (Building Blocks)
Monosaccharides:
are simple sugars commonly found in rings.
Mono=one, Saccharide=sugar

4. Carbohydrate Monomers (Building Blocks)
Monosaccharides Examples:
Glucose: commonly found in blood of animals
Galactose: a simple sugar found in milk
Fructose: commonly found in fruit

5. Carbohydrate Monomers (Building Blocks)
Glucose

6. Carbohydrate Polymers
Polysaccharides:
Poly=Many, Saccharide=sugar
Polysaccharides are made by linking monosaccharides together.
They can be very large and complex.

7. Carbohydrate Polymers
Disaccharides: Di=Two, Saccharide=sugar Disaccharides contain 2 monosaccharides joined by dehydration synthesis.

8. Carbohydrate Polymers
Dissacharide Examples:
2. Sucrose:
“Table Sugar”
Made up of
Fructose + Glucose
1. Lactose:
Found in Milk
Made up of
Galactose + Glucose 8

9. Carbohydrate Polymers
Complex Carb (Larger polysaccharide) examples
1. Starch: a form of glucose in plants
(breads, pasta, potatoes)

10. Carbohydrate Polymers
Complex Carb (Larger polysaccharide) examples
2. Cellulose: contained in the cell walls of plants; gives strength and rigidity to plant cells.

11. Carbohydrate Polymers
Complex Carb (Larger polysaccharide) examples
3. Glycogen: a common storage form
of glucose in animals (stored in the
muscles and liver to be used as
quick energy)
