Question

Which of these is a polysaccharide?
A. Lactose
B. Glycogen
C. Sucrose
D. Maltose

Answer 1

Polysaccharides are the most common forms of carbohydrates in our food. When bound together by a bond of glycosides, the monosaccharides form the polysaccharides.

Complete answer:
Glycogen and starch are the most common kind of polysaccharides. The other kinds of polysaccharides are classified as structural chitin and cellulose-like polysaccharides. They are also known as polysaccharide storage. The glycogen is retained in adipose tissue for a long period of time, called triglycerides, and it(glycogen) is secreted by raising the insulin counts. The glycogen is then separated into glucose molecules. The liver carries it along with the stored glycogen into the brain, and the spinal cord. The glycogen is alloyed. Glycogen is found in the cell wall of some species.
The polymer of glucose as glycogen. Glycogen has an amylopectin-like structure with the alpha 1,4 glycosidic linkage and alpha 1,6 glycosidic linkage connection between two glucose chain units. It is used in the muscles as a storage reserve. The glycogen is converted into glucose by muscle glycogenolysis, and through the glycolysis phase, the glucose produces energy as ATP to the muscles.
Lactose is glucose- and galactose-forming disaccharide.
Sucrose is glucose- and fructose-formed disaccharide.
Maltose is a glucose monomer disaccharide.
Hence, choice B is the right answer.

Note: In his study of glycogen as the 'sugar-forming material' in the liver, Claude Bernard was the first scientist to identify glycogen in 1857. Kekule developed the empirical glycogen formula in 1858 and was later discovered to be present in muscular tissue as well. The glucose-composed disaccharides are lactose and maltose.
