Sucrose is NOT a reducing sugar since
Sucrose is NOT a reducing sugar since
Updated On: May 30, 2022
- it is chemically stable
- it contains no free aldehyde or keto group adjacent to , $>CHOH$ group
- it is built up of a fructose unit
- it is optically active

The Correct Option is B
Solution and Explanation
Carbohydrates which can reduce Tollen's reagent or Fehling solution are called reducing sugars. All the monosaccharides and the disaccharides (except sucrose) are reducing agent.
Sucrose does not have free aldehyde or keto group adjacent to $> CHOH $ group, therefore it fails towards Tollen's reagent and Fehling solution.
Sucrose does not have free aldehyde or keto group adjacent to $> CHOH $ group, therefore it fails towards Tollen's reagent and Fehling solution.

Enzymes
Catalysts of biological systems can be known as Enzymes. Enzymes helps us to perform the huge variety of biochemical reactions that encompass in life are all mediated by a series of activities.
Properties of Enzymes:
Following are the properties of enzymes:
- Enzymes initiate and speed up the reaction
- The enzyme’s activity is ph dependent
- Enzymes have the capacity to forward and reverse the reaction but do not decide the direction of the biochemical pathway
- An enzyme has a particular area on which the substrate interacts to produce the desired product
- Enzyme becomes unstable at varying ph, high temperature and heat
- It have protein like characteristics
- Substrates can be catalyzed with a small number of enzymes
- Enzyme activity represents absolute, relative, group and stereo specificities
- Some enzymes perform regulatory function
- It minimise activation energy (Ea)
- The enzymes remain unaffected before and after the product formation and it can be reused
- They are soluble both in water and NaCl.
