The Fehling's and the Benedict's Test are the just two of the many tests conducted in identifying reducing and non-reducing sugars. Reducing sugars like the monosaccharides can reduce cupric hydroxide from the reagents used.
This is because the reducing sugars have a free oH group at their anomeric carbon that can cause the reduction of mild oxidizing agents like fehling and Benedict solution.In non reducing sugars this oH is involved in glycosidic bond formation.
What else can I help you with?
Does orange contain reducing sugars?
Yes, it is true.
How would benedict's solution mixed with starch and saliva react?
Benedict's solution is used to test for the presence of reducing sugars. When mixed with starch and saliva, the reaction would depend on whether the starch in the solution has been broken down by the enzyme amylase present in saliva into simpler sugars. If starch is broken down into reducing sugars like maltose or glucose, then the Benedict's solution would change color from blue to green, yellow, orange, or red, indicating a positive result for reducing sugars.
Explain the results of trommer's test in starch?
Trommer's test is a chemical test used to detect the presence of reducing sugars in a sample. In the case of starch, which is a polysaccharide and not a reducing sugar, Trommer's test will typically result in a negative outcome. This is because starch does not contain a free aldehyde or ketone group required to react with the reagents used in the test.
Why has water been included as one of the test materials for reducing sugars starch and protein?
sugars and starch are both made only of carbon, hydrogen and oxygen that is insoluble in cold water or alcohol
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.
Can saliva dissolve sugar?
No, saliva doesn't contain reducing sugars, but it does contain enzymes that break down starch. Even so, starch is not a reducing sugar either - it is a polysaccharide.
Does bread contain non-reducing sugars?
no it does not
Does water contain reducing sugars or polysaccharides?
Normal bottled water has no sugars. If it is vitamin water or flavored water it will have some.
Does orange contain reducing sugars?
Yes, it is true.
Which carbohydrate is more complex reducing sugar or starch?
Starch is a more complex carbohydrate than reducing sugar. Reducing sugars are simple carbohydrates that can reduce other compounds, while starch is a complex carbohydrate made of many sugar units linked together in a more elaborate structure.

What tests show that starch is broken down to sugars?
Amylase enzyme tests can confirm the breakdown of starch to sugars. Benedict's reagent can be used to detect reducing sugars like glucose. Additionally, an iodine test can show the absence of starch by changing color from blue-black to brown.
Why did the potato juice test negative in the benedict's reagent test?
The potato juice likely tested negative in the Benedict's reagent test because it does not contain reducing sugars, such as glucose or fructose, which are necessary to form a positive reaction with Benedict's reagent. Potatoes primarily consist of starch, a polysaccharide that is not a reducing sugar, explaining the negative test result.
Do fructose and glucose contain reducing sugars?
No, it is a polysaccharide and like other polysaccharides it is a non reducing sugar.
