Question

Cellulose is a
(A) Hex Polysaccharide.
(B) Penta Polysaccharide.
(C) Tri Polysaccharide
(D) None of these.

Answer 1

Hint :We know that we have come across the word linear multiple times. We can expect a linear polymer to be a long continuous chain of carbon–carbon bonds with the remaining two valence bonds attached primarily to hydrogen.

Complete Step By Step Answer:
Cellulose is a very essential structure of cell walls in green plants and may be in some algae etc. Cellulose is present in abundance in Earth’s surface as organic polymer cellulose is also used in the production of paper and paperboard. When the cellulose is present in smaller quantities it can be used to derive the product of rayon and cellophane. Cellulose is one of many polymers found in nature. Wood, paper, and cotton all contain cellulose.
In humans cellulose cannot be digested it is an insoluble dietary component and comes out directly in the faces. Cellulose does not consist of any taste and smell because it's hydrophilic in nature and it is not soluble in water. Cellulose is an excellent fiber. Wood, cotton, and hemp rope are all made of fibrous cellulose. Cellulose is made of repeat units of the monomer glucose. This is the same glucose which our body metabolizes in order to live, but we can't digest it in the form of cellulose. Because cellulose is built out of a sugar monomer, it is called polysaccharides.
Therefore the correct answer is option D, because cellulose is a linear polysaccharide.

Additional Information:
The cellulose can be converted from energy crops to biofuels which is known as cellulosic ethanol and is a part of renewable sources of energy. While using the cellulose in industries we extract the cellulose from cotton or wood pulp and cellulose is also found in the ruminants for termites which can digest the cellulose by any symbiotic relationship. r. Cellulose can be condensed through the glycosidic bond. In cellulose there is no branching or coiling of the molecule because it is a straight chain compound cellulose often provides high tensile strength to the plants and their stems and it is further distributed into the matrix of Lignin.

Note :
Remember that we can conclude that a polymer consisting of a single continuous chain of repeat units is called linear polymers. The linear polymers are well packed and have high magnitudes of intermolecular forces of attraction and therefore have high densities, high tensile strength and high melting points.
