What are 3 polymers made of glucose monomers

The polymers made of glucose monomers are usually carbohydrates, which are known as condensation polymers.  From this description, we can know that example of glucose monomers are starch, which is made up of hundred of glucose monomers that will separate the water molecules. Another is glycogen which is the energy reserve in animals compared to starch which is a reserve in plants. Glycogen is reserved in the liver and skeletal muscle tissues of animals. The third one is cellulose. Cellulose’s natural form is cotton, also the purest.  It is also known as the most abundant organic compound that can be found on Earth.
