Types of Carbs
Monosaccharides (monomers)

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
Glucose, Fructose, & Galactose


All are written
C6H12O6
Their structures are
different!
Same chemical
formula, but different
structural formula

Disaccharides

2 monomers added
together

Example:
Table Sugar =
glucose + fructose
Polysaccharides

3 or more monomers
added together
How are carbs stored?

Glycogen in
animals
