Maltose is the polymer of glucose and glucose.

Lactose is the polymer of glucose and galactose.

Examples of this Biomolecule

Functional Groups

The primary three are aldehydes, ketones, and alcohols.


1. Energy for cells

2. Structural support

3. Cell to cell communication


1. Animal cells polymerize sugar, so they store energy.

2. The structure is nearly indigestible, good for maintains structure.

3. Cell adhesion helps distinguish each cell. Infinite combinations due to 3 dimensional structure. This helps differentiate between self and non-self.
