The Molisch test is not positive in substances that do not contain carbohydrates or those that do not readily form a purple complex with α-naphthol in the presence of sulfuric acid. This includes pure fats, proteins, and some non-carbohydrate organic compounds. Additionally, certain modified or degraded carbohydrates may also yield a negative result.
What else can I help you with?
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.
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 is the chemical basis for a positive test in Molisch's test?
See this link.
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.
Is molisch's test is specific test for glucose?
what is the name of result from molisch test
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.
Viva voce for molisch test?
The Molisch test is used to detect the presence of carbohydrates in a given sample. During a viva voce for the Molisch test, you may be asked to explain the principle of the test, demonstrate how it is performed, and interpret the results obtained. Be prepared to discuss the formation of a purple ring when positive for carbohydrates due to the reaction between α-naphthol and sulfuric acid.
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 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.
