Cellulose, the most important constitutent of plant cell wall is made ...
Cellulose is the most abundant organic compound on Earth and is the primary structural component of plant cell walls. It is a complex carbohydrate, specifically a polysaccharide, made up of repeating units of glucose molecules. The correct answer to the question is option 'C': an unbranched chain of glucose molecules linked by β-1, 4 glycosidic bonds.
Explanation:
Cellulose is a linear polymer composed of glucose units. The glucose molecules are linked together by glycosidic bonds, which are covalent bonds formed between the anomeric carbon of one glucose molecule and the hydroxyl group of another glucose molecule. In cellulose, the glycosidic bonds are β-1, 4 bonds, meaning that the hydroxyl group attached to the first carbon of one glucose molecule is linked to the fourth carbon of the next glucose molecule. This creates a long, unbranched chain of glucose units.
Key Points:
- Cellulose is a complex carbohydrate and the main constituent of plant cell walls.
- It is composed of repeating units of glucose molecules.
- The glucose molecules are linked together by glycosidic bonds.
- In cellulose, the glycosidic bonds are β-1, 4 bonds.
- The β-1, 4 bonds create an unbranched chain of glucose units.
The other options in the question are incorrect for the following reasons:
a) An unbranched chain of glucose molecules linked by α-1, 4 glycosidic bonds: This is incorrect because cellulose is linked by β-1, 4 glycosidic bonds, not α-1, 4 bonds.
b) A branched chain of glucose molecules linked by β-1, 4 glycosidic bonds in straight chain and α-1, 6 glycosidic bonds at the site of branching: This is incorrect because cellulose is an unbranched chain and does not contain α-1, 6 glycosidic bonds.
d) A branched chain of glucose molecules linked by α-1, 6 glycosidic bonds at the site of branching: This is incorrect because cellulose does not contain α-1, 6 glycosidic bonds.
