Simple sugars
C:H:O are in a
1:2:1 ratio
Examples:
Glucose – energy for cells
Fructose – makes fruit sweet
Galactose – sugar in milk

5. Glucose, Fructose, & Galactose
All are written C6H12O6
Their structures are different!
Same chemical formula, but different structural formula

6. Disaccharides 2 monomers added together Example: Table Sugar =
glucose + fructose

7. Polysaccharides
3 or more monomers added together

8. How are carbs stored?
Glycogen in animals
Starch in plants
Cellulose
