Spare Protein and Fat for Other Uses
Polysaccarides
Starch
Used for storage
Insoluble
Made of 2 polymers
Amylose
Amylopectin
Glycogen
Storage in animals
Fast Hydrolysis
Lots of short branches
Cellulose

Dissaccarides
Formed when two monosaccarides join
Through condensation
One monosaccaride loses H and other loses OH
Water molecule is removed
Forms a glycosidic bond
Examples
Sucrose
Glucose and Fructose
Maltose
Glucose and Glucose
Lactose
Glucose and Galactose
Found in three forms
Disaccarides
