Why is fructose a reducing agent?
Fructose is a reducing agent because it has a free aldehyde group (on carbon-1) that can undergo oxidation reactions by donating electrons to other compounds, thus reducing them. This makes fructose capable of reducing other substances by itself being oxidized in the process.
What is the dextrose equivalent of fructose?
the dextrose equivalent of fructose is 100
Is fructose gives positive test with tollens reagent?
Fructose does not give a positive test with Tollens' reagent because it is a reducing sugar that does not have a free aldehyde group capable of reducing the Tollens' reagent. Tollens' reagent is typically used to detect the presence of aldehydes but may not react with fructose due to its ketone functional group.
Stachyose a reducing sugar?
Yes, because the galactose derivative's C2 (the carbonyl carbon) can ring open to form an aldehyde.
Does cucumber contain reducing sugar?
Yes, cucumbers contain small amounts of reducing sugars, such as glucose and fructose. These sugars are responsible for the slightly sweet taste of cucumbers.
Is reducing sugar present in apple?
yes fructose
Do fructose and glucose contain reducing sugars?
No, it is a polysaccharide and like other polysaccharides it is a non reducing sugar.
Is glucose and fructose reducing sugars?
yes, both glucose and fructose are reducing sugars. but the sucrose is non-reducing sugar although it is formed from two reducing sugars.

Is fructose a reducing sugar?
Yes. It is a monosaccharide. Although it does not contain an aldehyde group, it can isomerise into an aldose.
Why doesn't aspartame react in Benedict's soluion?
It's not a reducing sugar. In fact, it's not a sugar at all. Benedict's solution gives a positive test, brick-red precipitate, with reducing sugars such as glucose and fructose.
Is xylose a reducing sugar?
Ribose: Ribose is an Aldopentose sugar, and all aldose sugars are reducing sugars. The non-reducing sugars are ketose sugars which contain a ketone functional group. For ex: Ketose = Sucrose. For ex: Aldose = Glucose, Fructose, Lactose
What will be formed when the monomer of glycogen binds to fructose?
The glycogen is polymer of glucose. So glucose is monomer of glycogen. You get one molecule of glucose and one molecule of fructose from one molecule of cane sugar. So when one molecule of glucose will combine with one molecule of fructose, you will get one molecule of cane sugar.
Why is the Benedict test not exclusive to glucose?
The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
Why sucrose is non reducing sugar?
Sucrose has a anomeric carbon which is not free since the carbon links glucose and fructose and fructose doesn't have free OH group to under reducing reaction and to open the ring so sucrose is non reducing. In the formation of sucrose ,1,2glycosidic bond is formed between glucose and fructose. In the process, the keto group on Carbon-2 of the fructose molecule and the aldehyde group on Carbon 1 of the glucose molecule are altered. Know that keto group and aldehyde group give a monosaccharides and disaccharides the reducing properties. Sucrose is a non-reducing sugar because it does not have free ketone or aldehyde group in its ring form because sucrose has no hemiacetal linkage sucrose is a disaccharide as it contains glucose and fructose linked by a glycosidic linkage. it is non-reducing because it does not contain any free aldehyde or keto group.
Which is the sweetest natural sugar?
Fructose
