3. What are Carbohydrates?
And more

4. What are Carbohydrates?
Carbohydrates are macromolecules made up of
Carbon (C), Hydrogen (H), and Oxygen (O)
Found in a ratio of 1:2:1
Usually in ring structures (in aqueous solution)
Carbohydrates are the main source of energy for living things

5. Types of Carbohydrates
Monosaccharide – simple sugars, single rings of CxHxOx.
Examples include:
Glucose (draw this), Galactose, and Fructose
* Wherever there is an angle, there is a CARBON atom

6. Types of Carbohydrates
Disaccharide – A compound made of CxHxOx with 2 joined simple sugars
Examples include: Sucrose, Lactose, and maltose

7. Types of Carbohydrates

8. Types of Carbohydrates
Polysaccharide (complex carbohydrates) – large molecules formed by monosaccharide chains
In animals –
Glycogen: chains of glucose broken down when energy is needed.
ex). muscle contraction.

9. Types of Carbohydrates
Polysaccharide (complex carbohydrates) – large molecules formed by monosaccharide chains
In plants –
Starch: stored energy in the form of chains of glucose
Cellulose: chains of the monosaccharide Dextrose, found in cell walls
Cellulose 

10. Properties of Carbohydrates
Carbohydrates are broken down by a process called Hydrolysis

11. Properties of Carbohydrates
Carbohydrates are made from monosaccharides from dehydration reactions
