I think you mean D-fructose is leavorotatory. D is a convention that compares a steroisomer to glyceraldehyde and does not define the right/left roatoion of plane polarised light.

What happens during the inversion of sucrose?

Invert Sugar is a mixture of equal parts of Glucose (Dextrose) & Fructose resulting from the hydrolysis of Sugar (Sucrose). It is found naturally in friuts & honey and produced artficially for use in the food industry.


Which sugar is called invert sugar?

when sucrose is hydrolysed it turns into glucose and fructose. fructose is laevo rotatory whereas glucose is dextrorotatory sucrose is also dextrorotatory but amout of laevo rotation of fructose is able to overcome the dextro rotation of glucose. hence the product is laevo rotatory an d reactant dextrorotatory hence sucrose is an invert sugar.


How do you distinguish glucose and fructose?

Glucose is an aldose whereas fructose in a ketose. There is a simple qualitative test for distinguishing between D-Glucose and D-Fructose.


What ketohexose and aldohexose are present in melezitose?

Melezitose is composed of the ketohexose fructose, along with two units of the aldohexose glucose. It is a trisaccharide made up of glucose-fructose-glucose.

How does the Fischer projection of D-fructose differ from D-glucose?

In the Fischer projection, D-fructose has a ketone functional group on the second carbon, while D-glucose has an aldehyde functional group on the first carbon. Additionally, D-fructose is a ketohexose with a five-membered ring structure, while D-glucose is an aldohexose with a six-membered ring structure.

Can sucrose hydrolysis result L-glucose?

No, sucrose hydrolysis will not result in L-glucose. Sucrose is made up of glucose and fructose, but the hydrolysis of sucrose produces equal parts of glucose and fructose in their D form, not L-glucose.
