1. Carbohydrates

2. Carbohydrates Carbo = carbon (C) hydrate= water (H2O)
Recognizing a carb – Use the 1:2:1 ratio
C H2 O 1 carbon: 2 hydrogen: 1 oxygen
Which are carbohydrates?
C12H6O12 C20H20O10
C6H6O12 C8H4O8
C6H12O6 C4H8O4
C12H6O6 C7H20O7
C5H10O5 C18H63O9
C5H10O5

3. Carbohydrates Two types: Simple sugars: Simple sugars
Complex carbohydrates
Simple sugars:
Monosaccharides & disaccharides
Function: provide quick energy
Example: glucose & sucrose

4. Dehydration synthesis
Dehydration = taking water out
Synthesis = putting together
This is how bigger carbs are made

5. Practice Problems
Show a dehydration synthesis between one disaccharide and one monosaccharide.
Show a dehydration synthesis between three monosaccharides and one disaccharide.
Show a dehydration synthesis between four monosaccharides.

6. Carbohydrates Complex carbohydrates: Polysaccharides
Function: energy storage and structural support
Examples: starch, cellulose, chitin

7. Hydrolysis Reaction Hydro = water Lysis = to break
This is how carbs are broken down.

8. Practice Problems
Show a hydrolysis reaction that results in two monosaccharides.
Show a hydrolysis reaction that results in a disaccharide and two monosaccharides.
Show a hydrolysis reaction that results in three disaccharides.
