Question

Starch is polymer of

• A. Glucose
• B. Fructose
• C. Maltose
• D. Sucrose

Answer 1

The correct option is A Glucose

Starch is a polymer of glucose. It is formed by the attachment of glucose unit by glycosidic bonds. The basic formula of starch is (C${}_6$H${}_{10}$O${}_5$)n. It exists in two forms amylose and amylopectin. Amylose is formed by linkage of glucose by alpha 1,4 glucose unit. It is a linear polymer. Amylopectin is a branched polymer of glucose where two polymeric chains of glucose of alpha 1,4 glucose unit are linked by alpha 1,6 linkage.

So, the correct answer is option A.
