One subunit of sugar

ex: glucose, galactose, fructose

2 subunits of sugar

Ex: sucrose (glucose + fructose)

* Monosaccharides combine in a dehydration reaction that forms water

[image]

Multiple sugar units

ex: glycogen (lots of glucose) and cellulose

*Glycogen- sugar storage in the liver

*Cellulose- insoluble fiber, made by plants

Biomolecules that are not soluble in water

ex: fatty acids

Carbon chains and a carboxyl group
