Question

Which of these is a polymer of fructose?
A.Glycogen
B.Starch
C.Inulin
D.Raffinose

Answer 1

Hint: Fructose which is also called fruit sugar is a simple ketogenic monosaccharide which is found in many plants. It combines with glucose to form sucrose.

Complete answer:
Fructose is a dietary monosaccharide along with glucose and galactose which can be easily absorbed by the blood during the process of digestion. It is mainly found in honey, tree and vine fruits, berries and flowers. Let us analyze the option to find the correction answer for the polymer of fructose.

Option A: Glycogen is the multibranched polysaccharide of glucose monomers that is the storage of energy in the body. The energy stored in the form of glycogen can be used anytime by its breakdown. It is usually stored in the adipose tissues in the form of fat. Therefore, this is the incorrect option.

Option B: Starch is a polysaccharide which comprises glucose monomers joined byα 1,4 linkages. The simplest form of starch is the linear polymer amylose while amylopectin is the branched form. Starch is white granular substance produced by all green plants. Therefore, this is the incorrect option.

Option C: Inulin is a heterogeneous polysaccharide of fructose monomers which consists of 2->1 linked beta-d-fructosyl residues with an (1->2) alpha-d-glucose end group. Therefore, this is the correct option.

Option D: Raffinose is a trisaccharide which is composed of galactose, glucose, and fructose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, other vegetables, and whole grains. Therefore, this is the incorrect option.

Hence, the correct answer is option (C)

Note: 1.The number of fructosyl residues can range from 2-60 in inulin.
2.Inulin is used to measure kidney function of the body.
