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.
The chemical formula of Dextrose is C6H12O6. Dextrose is the name sometimes given to dextrorotatory glucose, which is in turn shortened 'D-glucose'.
When d-glucose reacts with bromine in water, a bromine atom may add to the glucose molecule, resulting in the formation of α-D-glucose bromide. This reaction can occur at the C1 or C6 position of the glucose molecule, leading to the formation of different bromo-glucose derivatives.
Oxygen:) hope this helped Have a great day :) :p :D
The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.

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.
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.
Glucose is an aldose whereas fructose in a ketose. There is a simple qualitative test for distinguishing between D-Glucose and D-Fructose.
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.
Fructose and glucose are found in sucrose.
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.
a molecule of fructose and a molecule of glucose
Glucose.
glucose, fructose. and galactose! :D
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.
The penultimate carbon on D-fructose is the fourth carbon (C4) in the linear chain.
The products of the reduction of D-fructose by NaBH4 is a 50-50 production of sorbitol and mannitol. These are the alditol forms of glucose and mannose respectively.
