yes, both glucose and fructose are reducing sugars. but the sucrose is non-reducing sugar although it is formed from two reducing sugars.

Are glucose and fructose reduced sugars?
Glucose and fructose are reducing sugars.
Do fructose and glucose contain reducing sugars?
No, it is a polysaccharide and like other polysaccharides it is a non reducing sugar.
Why sucrose does not give a positive Benedict's test but hydrolyzed sucrose does give a positive beneditcts test?
Sucrose is formed from glucose and fructose.Sucrose is formed from glucose and fructose. Glucose and fructose gives positive test for benedict becuz both of them are reducing sugars whereas sucrose is not a reducing sugar so it gives negative test for benedict. On prolonged heating,sucrose will form glucose and fructose (reducing sugars)which ultimately gives a positive result .
Are the products of sucrose hydrolysis reducing sugars?
No, sucrose is not a reducing agent. The disaccharide sucrose can be 'inverted' breaking the molecule into the monosaccharides glucose and fructose, both of which are reducing sugars. This is commonly done by enzymatic action.
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.
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 is fructose and glucose examples of?
Sugars.
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 sugars are in bananas?
sucrose, fructose and glucose.
What are glucose fructose and ribose examples of?
Sugars.
What happens when Fehling's solution is mixed with sucrose?
The sucrose does not react with Fehling's reagent. Sucrose is a disaccharide of glucose and fructose. Most disaccharides are reducing sugars, sucrose is a notable exception, for it is a non-reducing sugar. The anomeric carbon of glucose is involved in the glucose- fructose bond and hence is not free to form the aldehyde in solution.
Which sugars are reducing?
glucose
