simply because they are carbohydrates, all carbohydrates produces positive result in molisch's test

All carbohydrates i.e. monosacchardes, dissacharides and polysaccharides are dehydrated (lose water) by a dehydrating agent (e.g. Sulphuric acid) they form aldehydes known as furfurral. The furfurral reacts with a component known as 1- naphthol present in Molisch reagent resulting in a reddish violet colour forming between the Reagent and the previous mixture of the carbohydrate and thedehydrating agent. It is important to note that the reaction is more rapid with simple sugars or monosaccharides

Will disaccharides and poly saccharides give a positive result to molisc test?

Yes, both disaccharides and polysaccharides will give a positive result in a Molisch test. The Molisch test detects the presence of any compound containing a significant amount of glycosidic bonds, which are present in both disaccharides and polysaccharides.


Will disaccharides and polysaccharides give positive result for molisch test?

Yes they will. Disaccharides will give a positive result much quicker than polysaccharides, and it also depends on the conditions because they need to be dehydrated by an agent such as concentrated H2SO4 and it so happens that it is much easier to do so on a disaccharide than it is on the polysaccharide


Why is the molisch test slower with disaccharides?

The Molisch test detects carbohydrates by breaking them down to monosaccharides. Disaccharides need to be hydrolyzed into their constituent monosaccharides before they can react with the Molisch reagent, which makes the test slower compared to monosaccharides that can react directly.


Why albumin gives positive Molisch test?

Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates


Does Benedict test indicate monosaccharides polysaccharides and disaccharides?

The Benedict test is useful for monosaccharides and disaccharides.


What does a positive Molisch's test on an unknown substance indicate?

A positive Molisch's test result indicates the presence of carbohydrates.


What is the positive result for molisch test?

all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.


Why does glycoproteins reacts positively with Molisch reagent?

Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.

What group of substance that give positive reaction to molisch test?

Carbohydrates typically give a positive reaction to the Molisch test. This is because the Molisch reagent reacts with the carbohydrates to form a purple complex, indicating the presence of sugar molecules in the solution.


Why egg albumin gives the negative result for molisch test?

Egg albumin gives a negative result for the Molisch test because it does not contain carbohydrates. The Molisch test is used to detect the presence of carbohydrates, and since egg albumin consists mainly of proteins with little to no carbohydrates, it does not react with the reagents used in the Molisch test to give a positive result.
