Question
What are the hydrolysis products of sucrose?
Solution
Sucrose on hydrolysis gives one unit of glucose and one unit of fructose.
\[\ce{\underset{Sucrose}{C12H22O11} + H2O ->[Invertase][or H3O+] \underset{Glucose}{C6H12O6} + \underset{Fructose}{C6H12O6}}\]

Assertion: Deoxyribose, \[\ce{C5H10O4}\] is not a carbohydrate.
Reason: Carbohydrates are hydrates of carbon so compounds which follow \[\ce{C_x(H2O)_y}\] formula are carbohydrates.
The following questions are case-based questions. Read the passage carefully and answer the questions that follow:
| Carbohydrates are optically active polyhydroxy aldehydes and ketones. They are also called saccharides. All those carbohydrates which reduce Fehling's solution and Tollen's reagent are referred to as reducing sugars. Glucose, the most important source of energy for mammals, is obtained by the hydrolysis of starch. Vitamins are accessory food factors required in the diet. Proteins are the polymers of α-amino acids and perform various structural and dynamic functions in the organisms. Deficiency of vitamins leads to many diseases. |
