Question
Which of the following statements is not true about sucrose?
A.
It is anon reducing sugar
B.
The glycosidic linkage is present
between $${C_1}$$ of $$\alpha $$ - glucose and $$C_1^ - $$ of $$\beta $$ - fructose
C.
It is also named as invert sugar
D.
On hydrolysis, it produces glucose and fructose
Answer :
The glycosidic linkage is present
between $${C_1}$$ of $$\alpha $$ - glucose and $$C_1^ - $$ of $$\beta $$ - fructose
Solution :
Sucrose contains glycosidic link between $${C_1}$$ of $$\alpha {\text{ - }}D$$ glucose and $${C_2}$$ of $$\beta {\text{ - }}D{\text{ - }}$$ fructose.
$${C_{12}}{H_{22}}{O_{11}} + {H_2}O \to {\text{Glucose + Fructose}}$$
Sucrose contains glycosidic link between $${C_1}$$ of $$\alpha {\text{ - }}D$$ glucose and $${C_2}$$ of $$\beta {\text{ - }}D{\text{ - }}$$ fructose.
$${C_{12}}{H_{22}}{O_{11}} + {H_2}O \to {\text{Glucose + Fructose}}$$
