Which sugar is called invert sugar ? Why it is called so ? |
| Answer» Solution :Sucrose is called invert sugar. Sugar is obtained as DEXTROROTATORY NATURALLY. When HYDROLYSED sucrose give D-GLUCOSE and D-fructose in equimolar MIXTURE. Glucose is dextrorotatory `(+52.5^(@))` and fructose is laevorotatory `(-92.4^(@))` and as a result, the net resultant mixture is laevorotatory. This product changes from dextro (+) to laevo (-) after hydrolysis is called invert sugar. | |
