The Molisch test is not typically used for brain lipid detection. It is commonly used to detect the presence of carbohydrates in a sample by forming a purple ring in the presence of carbohydrates. For brain lipid detection, techniques like thin layer chromatography or mass spectrometry are more commonly employed.

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.
What is the composition of molisch test?
Molisch test reagent is composed of alpha-naphthol dissolved in ethanol.
What is the importance of Molisch's test performed on carbohydrates?
Molisch's test is important for detecting the presence of carbohydrates in a solution. It involves the addition of alpha-naphthol and sulfuric acid, which react with the carbohydrates to form a purple color. This test is useful in biochemical and biological studies to identify the presence of sugars.
Why purple colour give in Molisch test?
The purple color in the Molisch test is due to the formation of a complex between the carbohydrate present in the sample and the alpha-naphthol reagent used in the test. This complex formation indicates the presence of carbohydrates in the sample.
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.
Is molisch's test is specific test for glucose?
what is the name of result from molisch test
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 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 albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
What does a positive Molisch's test on an unknown substance indicate?
A positive Molisch's test result indicates the presence of carbohydrates.
Name the 2 tests of carbohydrates anaylsis that are based on the reduction of Copper ions.Select one:a. Benedict’s and barfoed’s testb. Barfoed’s test and molisch testc. Molisch test and iodined. Salivanof and osazonee. Benedict’s and iodine test?
Molisch Test and iodine.
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.
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.
What is the chemical basis for a positive test in Molisch's test?
See this link.
What is the composition of molisch test?
Molisch test reagent is composed of alpha-naphthol dissolved in ethanol.
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.
What is the general test used for carbohydrates?
i think the general test for carbohydrates is Molisch Test..
