Final answer:
Beta-glucose polymer carbohydrates include cellulose, starch, and glycogen, which are all polysaccharides with different structures and functions. Cellulose provides structural support in plants, while starch and glycogen are used for energy storage in plants and animals, respectively. Lactose is a disaccharide made of glucose and galactose, linked by a beta-glycosidic bond.
Step-by-step explanation:
Beta-Glucose Polymer Carbohydrates
Examples of beta-glucose polymer carbohydrates include cellulose, starch, and glycogen. These are all polysaccharides that serve different functions in biological organisms. Cellulose is a linear polymer of glucose that provides structural support in plant cell walls. Starch, which includes amylose and amylopectin, is the primary energy storage in plants. Glycogen, similar in structure to amylopectin, is the main form of glucose storage in animals and bacteria.
These three polysaccharides consist of glucose units linked by glycosidic bonds, but they differ in their structure and properties. Cellulose has a linear arrangement allowing it to form fibers that give strength to plant cell walls. On the other hand, both starch and glycogen are branched polymers, making them suitable for energy storage because they can be more readily broken down into glucose when required by the organism.
The Bond in Lactose
Lactose is a disaccharide composed of two monosaccharides, glucose and galactose, joined by a beta-glycosidic bond. This type of bond links the molecules together and is crucial for the carbohydrate's role and digestibility in human nutrition.
