A) cellulose
B) starch
C) glucose
D) glycogen
Correct Answer: D
Solution :
Glycogen is the reserve food in animals that why it is also called animal starch. It is found mainly in liver and muscles. Chemically it is analogous to starch but it is more extensively branched than amylopectin. The linkage and monosaccharides units are similar. About 500 15000 glucose units make up glycogen. It is non-reducing sugar and gives red colour with iodine. Starch, a polymer is D-glucopyranose unit linked by \[\alpha \]-1,4-glycosidic linkages. It consists of a mixture of amylose and amylopectin of 1 : 4 ratio. Starch in partial hydrolysis results in substances called dextrins. It is easily digested thats why given to infants for feeding or patients. Cellulose is the most important structural components of the cell wall of plants. It is a linear polymer of \[\beta \]-D glucose units connected through (\[\text{ }\!\!\beta\!\!\text{ }\]-1,4-glycosidic linkage. Glucose or D-glucose is most widely distributed sugar. It is known by the name of blood sugar also. It is a component of sucrose.
