Polysaccharides:
* Starch: A storage polysaccharide found in plants. It's made up of long chains of glucose molecules linked together.
* Glycogen: A storage polysaccharide found in animals, particularly in the liver and muscles. It's a highly branched structure of glucose molecules.
* Cellulose: A structural polysaccharide found in plant cell walls. It's a straight chain of glucose molecules linked together in a specific way that makes it strong and rigid.
* Chitin: A structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi. It's similar to cellulose but contains a nitrogen-containing group on each glucose molecule.
Disaccharides:
* Sucrose (table sugar): A disaccharide made up of glucose and fructose.
* Lactose (milk sugar): A disaccharide made up of glucose and galactose.
* Maltose (malt sugar): A disaccharide made up of two glucose molecules.
Other molecules:
* Glycoproteins: Proteins with attached carbohydrate groups (including glucose). These play a role in cell recognition, signaling, and other functions.
* Glycolipids: Lipids with attached carbohydrate groups (including glucose). These also play a role in cell recognition and signaling.
* Nucleotides: The building blocks of DNA and RNA. While not directly made up of glucose, glucose is involved in the synthesis of these molecules.
So, glucose is a fundamental building block for many different molecules in living organisms!
