Question

Sucrose on hydrolysis gives

• A. $\beta-D-Glucose$ + $\alpha -D-Fructose$
• B. $\alpha-D-Glucose + \beta - D - Glucose$
• C. $\alpha-D-Glucose + \beta -D-Fructose$
• D. $\alpha-D-Fructose + \beta -D-Fructose$

Answer 1

The Correct Option is C

The correct answer is Option C) \(\alpha-D-Glucose + \beta -D-Fructose\)

Sucrose is a disaccharide made up of two monosaccharides, namely, glucose and fructose. Sucrose is naturally produced in plants and is refined to form edible table sugar. The molecular formula of sucrose is C₁₂H₂₂O₁₁. 

The two monosaccharides in sucrose are held together by glycosidic linkage. Upon hydrolysis, this glycosidic linkage is broken to yield two molecules of \(\alpha\) - D - glucose and \(\beta\) - D - fructose. The reaction can be written as:

\(C_{12}H_{22}O_{11}+H_{2}O \to\underset{\text{D(+)Glucose}}{{C_{6}H_{12}O_{6}}}+\underset{\text{D(-)fructose}}{{C_{6}H_{12}O_{6}}}\)

Answer 3

The correct answer is Option C) \(\alpha-D-Glucose + \beta -D-Fructose\)

Sucrose is formed by the combination of two monosaccharides: Glucose and Fructose. The chemical formula of sucrose is C₁₂H₂₂0₁₁.  It is commonly known as cane sugar or table sugar.

Properties of Sucrose 

• The crystal structure of sucrose is monoclinic.
• The enthalpy of combustion for sucrose is 5647 kJ.mol⁻¹
• On combustion, sucrose forms carbon dioxide and water.
• It can be dehydrated with the help of sulphuric acid.
• There is a glycosidic bond between glucose and fructose
