glucose contains aldehydic group where as fructose contains ketonic group.

CHO-(CHOH)4-CH2OH - glucose

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 is the difference between sucrose glucose and fructose?

Sucrose is a disaccharide: it's a glucose molecule bonded to a fructose molecule. Its formula is C12H22O11.Glucose and fructose are monosaccharides, but the atoms are arranged differently. Pictures can't be posted here, but the structure of these two molecules is easy to find on the Web.


What two sugars combine to make sucrose?

Sucrose is a disaccharide composed of an alpha-glucose and an alpha-fructose. It has an alpha 1-2 glycosidic linkage between the two molecules.


How does the body differentiate between fructose and glucose during metabolism?

During metabolism, the body differentiates between fructose and glucose through different pathways. Glucose is mainly metabolized in the liver and raises blood sugar levels, while fructose is primarily metabolized in the liver and converted into fat. This difference in metabolism can have varying effects on the body, such as insulin sensitivity and fat storage.


What is the difference between glucose and frutose?

A different between fructose and glucose is that fructose is much sweeter than glucose. Also fructose, when eaten and absorbed, releases its energy slower than glucose and can metabolize without the need of insulin.


What is similar between glucose and fructose?

They are both sugars.


When you add Fructose and fructose does it gives you glucose?

No. Fructose and glucose are two different, simple sugars or monosaccharides. Fructose is a ketohexose. Glucose is an aldohexose.


What are the products of a condensation reaction between glucose and fructose?

The products of a condensation reaction between glucose and fructose are sucrose and water. In this reaction, a glycosidic bond forms between the glucose and fructose molecules, resulting in the formation of the disaccharide sucrose. Water is also produced as a byproduct of the condensation reaction.


How are fructose and glucose iffrent?

Glucose and fructose have the same chemical formula, C6H12O6, but different structural formulas, meaning that they differ in their three-dimensional structures (i.e. the way the atoms are bonded). Due to this difference, glucose is less sweet than fructose, which is the sweetest sugar.


What is the difference between fructose and glucose in terms of their effects on the body's blood sugar levels?

Fructose and glucose are both types of sugar, but they affect the body's blood sugar levels differently. Glucose is quickly absorbed into the bloodstream, causing a rapid increase in blood sugar levels. Fructose, on the other hand, is processed by the liver and does not cause as sharp of a spike in blood sugar levels. This difference can impact how the body metabolizes and stores these sugars.


What are the differences in the molecular structures of fructose and glucose?

Fructose and glucose are both simple sugars, but they have different molecular structures. Glucose has a six-carbon ring structure, while fructose has a five-carbon ring structure. This difference in structure affects how they are metabolized in the body and their sweetness levels.


What enzyme changes glucose to frutose?

The enzyme responsible for converting glucose to fructose is glucose isomerase. It catalyzes the reversible isomerization of glucose to fructose. This enzyme is commonly used in the production of high-fructose corn syrup.
