Hydrolysis of carbohydrates

The video tutorial explores the chemistry of carbohydrates and hydrolysis. It begins by defining carbohydrates, their structure, and classification into monosaccharides, disaccharides, and polysaccharides. The tutorial then explains hydrolysis, a water-based reaction that breaks down larger molecules like disaccharides and polysaccharides into monosaccharides. An example of sucrose hydrolysis is provided to illustrate the process.

What are the three elements always found in carbohydrates?

• Carbon, Oxygen, Sulfur

• Hydrogen, Oxygen, Nitrogen

• Carbon, Hydrogen, Oxygen

• Carbon, Nitrogen, Oxygen

Which type of carbohydrate cannot be hydrolyzed?

• Monosaccharides

• Oligosaccharides

• Disaccharides

• Polysaccharides

What is the main difference between hydrolysis and condensation reactions?

• Both reactions do not involve water.

• Hydrolysis uses water to break down molecules, while condensation uses water to join molecules.

• Hydrolysis and condensation both break down molecules.

• Condensation uses water to break down molecules, while hydrolysis uses water to join molecules.

What happens to sucrose during hydrolysis?

• It combines with another sucrose molecule.

• It breaks down into glucose and fructose.

• It forms a new disaccharide.

• It remains unchanged.

What type of bond is broken during the hydrolysis of sucrose?

• Hydrogen bond

• Glycosidic bond

• Peptide bond

• Ionic bond
