Question

Complete hydrolysis of cellulose gives

• A. D-fructose
• B. D-ribose
• C. D-glucose
• D. L-glucose

Hint:

A straight-chain polysaccharide, cellulose is made up of D-glucose units connected by -glycosidic bonds.

Answer 1

The Correct Option is C

The correct answer Option C) D-glucose

Partial hydrolysis of cellulose gives the disaccharide cellobiose \(({{C}_{12}}{{H}_{22}}{{O}_{11}})\) . Cellobiose resembles maltose (which on acid catalyzed hydrolysis yields two molar equivalents of \(D-\) glucose) in every respect except one: the configuration of its glycosidic linkage.

Answer 2

The correct answer is Option C) D-glucose

Real Life Applications

• D-glucose is a key ingredient in the production of several compounds in the chemical industry, such as ethanol, acetic acid, and sorbitol. While acetic acid is used to make plastics and other products, ethanol is utilized as a fuel. In foods and drinks, sorbitol is used as a humectant and a sweetener.
• D-glucose may be fermented to create ethanol, which can be utilized as a biofuel in the biofuel sector. Ethanol may be used to fuel automobiles directly or combined with petrol to provide cleaner fuel.
• D-glucose is a feed additive for cattle in the animal feed business. It gives animals energy and aids in their healthy growth and development. D-glucose is a sugar that is used in the food and beverage industry to sweeten baked products, soft drinks, and sweets. Jams, jellies, and syrups are also made with it.
• D-glucose is a common ingredient in the pharmaceutical industry's production of medications including insulin, vaccinations, and antibiotics. Drugs are also transported by it to the body.

Answer 3

The correct answer is Option C) D-glucose

A substance that is organic is cellulose. 

• The molecular symbol for it is (C₆H₁₀O₅)n. It is a complex carbohydrate made up of carbon, hydrogen, and oxygen.
• Tasteless and odorless, cellulose has neither.
• It is the primary polysaccharide utilized by plants for structural purposes.

Breakdown of Cellulose

The process of dissolving cellulose molecules is known as cellulolysis. 

• Cellodextrins are created when the molecules are divided into smaller polysaccharides.
• Additionally, they are totally decomposable into glucose units.
• An example of this is a hydrolysis reaction.
• Other polysaccharides find the cellulolysis process to be rather challenging because of the strong binding of cellulose molecules.
• The enzymes that dissolve the glycosidic bond in cellulose are known as glycoside hydrolases, and they include exo-acting glucosidases and endo-acting cellulases.
• These enzymes are often released as a component of multienzyme complexes, which may also include doctrines and modules that bind carbohydrates.
