1. Pasta vs Candy???

2. ORGANIC COMPOUND Carbohydrates

3. Carbohydrates Are needed for ENERGY “ose” endings Are made of C, H, O Have a 2:1 ratio of H:O Ring Structures Sugars, starches, cellulose, glycogen

4. Types of Carbohydrates 1. Monosaccharides  simple sugars –Glucose –Galactose –Fructose Isomers!!! –C 6 H 12 O 6 ONE DIAMOND!

5. Samples of Monosaccharides

6. Continue with Carbs… 2. Disaccharides  two monosaccharides together by dehydration synthesis –Maltose –Sucrose –Lactose C 12 H 22 O 11 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!

12. Hydrolysis Simplified!

13. Hydrolysis of CARBS! !
