Q. Starch is a polymer of

UP CPMTUP CPMT 2009Biomolecules

Solution:

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.
