Sucrose is a non reducing sugar.

. Galactose is a reducing sugar. Non-reducing sugars do not have an OH group attached to the anomeric carbon so they cannot reduce other compounds. The two aldopentoses are.

B Only aldoses but not ketoses are reducing sugars. Arises from inability to metabolize the disaccharide lactose b. Depends on a deficiency of sucrose in the diet c.

A galactose B gluconic acid C sucrose D b methyl galctoside. Show transcribed image text Expert Answer. Out of disaccharides sucrose is a well-known non-reducing sugar.

In such a reaction the sugar becomes a carboxylic acid. A sugar is classified as a reducing sugar only if it has an open-chain form with an aldehyde group or a free hemiacetal group. The monosaccharirdes have free aldehyde or keton group which can reduce Cu2to CuTherefore these are called reducing sugars.

A reducing sugar is any sugar that is capable of acting as a reducing agent. The sugar readily acts as an oxidizing agent. All monosaccharides such as glucose are reducing sugars.

D All disaccharides not monosaccharides are reducing sugars. OH Ho OH Ho 해 OH HO OH OH. OH Ho OH Ho 해 OH HO OH OH.

Which of the following is a reducing sugar. A All monosaccharides in either the ketose of aldose family are reducing sugars. Lactose is composed by the combination of a glucose and a galactose molecule.

In an alkaline solution a reducing sugar forms some aldehyde or ketone which allows it to act as a reducing agent for example in Benedicts reagent. They cannot be hydrolyzed into smaller units. Sugar is a substance which is crystalline sweet in taste and soluble in water.

Which of the following is a reducing sugar. All monosaccharides are called reducing sugars. This problem has been solved.

Monosaccharides are the simplest carbohydrates. Sucrose starch are non-reducing sugars. Which of the following is a reducing sugar.

β β -methyl galactoside. Glucose fructose mannose galactose are reducing sugar Explanation. Select all that apply A.

It undergoes mutarotation 4. Sucrose is a disaccharide formed by glycosidic linkage between C-1 of alpha-glucose and C-2 of asked Apr 17 in Chemistry by Shwetapandey 120k points. Which is true regarding reducing sugar.

E All glycosides are reducing sugars. A reducing sugar has a free aldehyde group or a free ketone group so it can act as reducing agent. For Teachers for Schools.

Arises because lactose is a dimer of galactose. It cannot react 3. It gives brownish red precipitate with Fehling reagent and with Benedicts reagent it gives yellow red or green precipitate confirming the presence of sugar.

E l e option B obstinacy and option the while option is not reducing sugar. The hydroxyl is fixed in either alpha or beta position. Monosaccharides which contain an aldehyde group are known as aldoses and those with a ketone group are known as ketoses.

C Only ketoses but not aldoses are reducing sugars. Correct answer for this problem while abs and h. All monosaccharides cannot be hydrolyzed further come under reducing sugar.

A alpha-D-fructofuranose B the methyl glycoside of cellobiose C ethyl. Ketoses must first tautomerize to aldoses before they will act as reducing sugars. Disaccharides which have aldehydic and ketonic group free act as reducing sugars eg.

The sugar readily acts as a reducing agent. Which one of the following is a reducing sugar. Lactose undergoes mutarotation and it is hence a reducing sugar.

-Disaccharides are formed from two monosaccharides and. 51 Which of the following is a reducing sugar. In this problem the reducing sugar Did you do you think so good.

Of the following which are characteristics of a reducing sugar. See the answer See the answer See the answer done loading. A disaccharide can be a reducing sugar or a non-reducing sugar.

A a-D-fructofuranose B the methyl glycoside of cellobiose C ethyl ß-D-glucopyranoside D methyl a-D-fructofuranoside E none of the above 52 Two D-aldopentoses give the same D-aldotetrose upon Ruff degradation. Which of the following is a reducing sugar. All monosaccharides are reducing sugars along with some.

The hydroxyl group on the anomeric C is bound to another sugar 2. Which one of the following is a reducing sugar. Which of the following is a reducing sugar.

Monosaccharides are considered as reducing sugars. Both tests employ alkaline solution of copper sulphate which is blue in colour with reducing sugar it gives orange to brick red precipitation. The sugar is an aldose.

Maltose and lactose are reducing sugars while sucrose is a non-reducing sugar. The correct option is C Sucrose. The sugar is a ketose.

Then sugar that cannot act as a reducing agent are non-reducing agents. Is based on the composition of lactose consisting glucose and fructose in glycosidic linkage d. A compound which acts as a reducing agent because of the presence of either ketoses or aldoses group forms a reducing sugar.
