Structure and Function of Homopolysaccharides

Which of the following is a homopolysaccharide?

• Peptidoglycan

• Hyaluronic acid

• Glycogen

• Heparin

Which one is incorrect about Glycogen?

• They are similar to starch but is more highly branched

• It can't dissolve in water

• Glycogen are commonly found in liver and muscles

• It is made up of many chains of sucrose joined by glycosidic bond

Which type of glycosidic bonds are found in glycogen?

• α-1,4 and α-1,6

• β-1,4 and β-1,6

• α-1,3 and α-1,6

• β-1,3 and β-1,6

What makes cellulose fibers strong?

• Hydrogen bonds between β-1,4 linked chains

• Cross-linking with proteins

• High solubility in water

• Extensive branching

Why is glucose stored as glycogen instead of in its free form?

• Free glucose is too reactive

• Glycogen prevents osmotic stress in cells

• Glucose molecules cannot cross the cell membrane

• Glycogen makes glucose non-polar
