Question

Starch is a polymer of

• A. glucose
• B. fructose
• C. sucrose
• D. maltose

Answer 1

Answer: (A)

Starch is polysaccharide consisting of various proportions of two glucose polymers, amylose and amylopectin. It occurs widely in plants, especially in roots, tubers, seeds and fruits, as a carbohydrate energy store. Starch is therefore a major energy source for animals. When digested it ultimately yields glucose. Starch granules are insoluble in cold water but disrupt if heated to foim a gelatinous solution.
