Question

What is cellulose?
A.Monosaccharide
B.Disaccharide
C.Homoglycan pentosan
D.Homoglycan hexosan

Answer 1

Hint: Cellulose is known to be the major component of the cell wall of plants. Cellulose is commercially used to produce papers, fibers, consumables as used for tablet formation, building material, and pharmaceutical purpose. Cellulose is the most abundant organic polymer which is found on Earth.

Complete step by step answer:Option -A- Monosaccharide
These are the simple sugars in which one oxygen atom, two hydrogen atoms are present for each carbon atom. They are also called reducing sugars. They are classified according to the number of carbon atoms present as trioses(3 Carbon), tetroses(4C), pentoses(5C), hexose(6C), heptoses(7C), and so on in this way.
Option -B- Disaccharide
These are formed by condensation reaction and these two polysaccharides are joined with the help of glycosidic bonds. Examples include maltose made up of two glucose units joined together by glycosidic linkage. Sucrose is formed by fructose and glucose molecules. Lactose is formed by glucose and galactose molecules.
Option -C- Homoglycan pentosan
These are polysaccharides having more number of simple sugars in them. Homoglycan means they are made up of one same sugar molecule in them having carbon atoms 5. These are types of polysaccharides.
Option -D- Homoglycan hexosan
These are defined as polysaccharides which are solely made up of one type of sugar/ monosaccharide. The single monosaccharide unit is a six-carbon atom sugar or hexose sugar. Examples include starch which is a lipopolysaccharide of glucose molecules and cellulose being a homopolysaccharide of many units of the hexose sugar glucose.
So, the correct answer to this question is the option"D".

Note:Polysaccharides are the most natural carbohydrates. They are also known as glycan. Therefore based on a single unit of polysaccharide they are made if they are classified into homoglycan having one same unit of sugar in them and heteropolysaccharide having two or more units of sugar in the polymer.
