ORGANIC COMPOUND

• Carbohydrates

3
Carbohydrates

• Are needed for ENERGY
• ose endings
• Are made of C, H, O
• Have a 21 ratio of HO
• Ring Structures
• Sugars, starches, cellulose, glycogen

4
Types of Carbohydrates

• 1. Monosaccharides ? simple sugars
• Glucose
• Galactose
• Fructose
• Isomers!!!
• C6H12O6

ONE DIAMOND!
5
Samples of Monosaccharides
6
Continue with Carbs

• 2. Disaccharides ? two monosaccharides together
  by dehydration synthesis
• Maltose
• Sucrose
• Lactose
• C12H22O11

TWO DIAMONDS!
7
Still More on Carbs

• 3. polysaccharide ? more than three
  monosaccharides combined
• Starch (plant energy storage)
• Glycogen (animal energy storage)
• Cellulose (in plant cell walls)

Lots of Diamonds!!
8
Dehydration Synthesis of Carbohydrates!!

• Monosaccharide monosaccharide ? disaccharide
  water

9
Condensation Reaction

• IS ANOTHER NAME FOR DEHYDRATION
  SYNTHESIS!!!!!!!!!!!!!!

10
Dehydration Synthesis Simplified!!
11
Hydrolysis is the REVERSE of dehydration synthesis

• Add water to break carbohydrates down into their
  building blocks!
