Any sugar that has an aldehyde or a ketone group in solution is termed a 'reducing sugar'
Glucose is a reducing because:
1: It shows a positive to Fehling's Test for reducing sugars by forming a brick red precipitate.
2: Straight chain monosaccharides can act as mild reducing agents, because the aldehyde group that is present can be oxidized to form a carboxylic acid group and also can form a carboxylate ion group in the presence of a base.
Ring form monosaccharide does not have aldehyde group thus are not consider as reducing sugars but they are readily in equilibrium with the open chain thereby becoming a reducing sugar.

Does benedict's solution need heating when testing for glucose?
It is part of the experiment to determine the sugar present... it does not react with non reducing sugar.
Is maltose non reducing sugar?
maltose is a reducing sugar ..
How can we identify reducing sugars?
A reducing sugar is any sugar that either has an aldehyde group or is capable of forming one in solution through isomerism. The cyclic hemiacetal forms of aldoses can open to reveal an aldehyde and certain ketoses can undergo tautomerization to become aldoses. However, acetals, including those found polysaccharide linkages, cannot easily become a free aldehyde. So glucose is one among them
Is Cellobiose is reducing or non reducing sugar?
It's a reducing sugar.
Is gentiobiose a reducing or non-reducing sugar?
a reducung sugar since it has an aldehyde group
Is glucose oxidizing sugar?
No glucose is non-reducing sugar.
What type of compound is C2H12O6?
Glucose. A reducing sugar.
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.
What are the sources of reducing and non reducing sugars?
Reducing sugarsThis glucose component makes it a reducing sugar. Lactose is found in human and cow milk. This glucose base makes maltose a reducing sugar. It can be found naturally in germinating grain, starches, and corn syrup in small amounts.Non reducing sugarsExamples include glucose,fructose, maltose and lactose. Those sugars which are unable to reduce oxidizing agents such as those listed above are called non-reducing sugars.
Does the Maillard reaction occur in a glucose-glycine mixture?
yes. this is because the glucose is the reducing sugar, it will participate in the Maillard reaction
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.
The chemical elements in a non reducing sugar?
frictose glucose lactose
Does starch gives positive result for Benedict test?
Starch is made up of repeating glucose units. Though it is a non reducing sugar, its hydrolysis gives out pure glucose, which is known as dextrose. And glucose, as we know, is a reducing sugar and hence would give a positive result in Benedict's test.
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
Is maltotriose a reducing sugar?
Trehalose is a non-reducing sugar because of the orientation of the second glucose molecule. This orientation places this glucose's anomeric, or "first" carbon directly in the 1,1-glycosidic bond. Because it is preoccupied, or "busy", it does not have any capabilities as a reducing sugar in oxidation-reduction reactions.
Does benedict's solution need heating when testing for glucose?
It is part of the experiment to determine the sugar present... it does not react with non reducing sugar.
