What does a positive Molisch's test on an unknown substance indicate?
A positive Molisch's test result indicates the presence of carbohydrates.
Is molisch's test is specific test for glucose?
what is the name of result from molisch test
Why albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
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 is the chemical basis for a positive test in Molisch's test?
See this link.
Why egg albumin gives the negative result for molisch test?
Molisch's test is used to detect carbohydrates. Egg albumen is free from carbohydrates.
What is a positive test for carbohydrates?

Molisch Test and iodine.
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 do disaccharides and polysaccharides give positive Molisch Test?
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
What is the importance of Molisch's test performed on carbohydrates?
Molisch's Test is a chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde. Its importance is that it tests the presence of carbohydrates based on their dehydration,
Why is molisch test used for brain lipid detection?
because there are such types of lipids that have carbohydrates attached to them(glycolipids). that's why Molisch test is used for lipid detection.
