Question

Glycogen is a homopolymer made of

• A. Glucose units
• B. Galactose units
• C. Ribose units
• D. Amino units

Answer 1

Answer: (A)

Glycogen is a branched polymer of glucose. It is readily soluble in water. It consists of alpha $D$ glucose units, mostly linked by $1-4$ glycosidic linkage, and is highly branched via frequent $1-6$ linkages.
So, the correct answer is 'Glucose unit'.
