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 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.
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.
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.
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
What is a positive test for carbohydrates?
These are the carbohydrate tests that would give a positive result on maltose: 1.Molisch test 2. Fehling's Test 3. Benedict's Test 4. Nylander's Test 5. Tollen's Test 6. Seliwanoff's Test 7. Barfoed's Test
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.
What is a glycoprotein or mucoprotein and how would they respond to the Molisch test?
A glycoprotein or mucoprotein is a type of protein that contains carbohydrate groups attached to it. In the Molisch test, these glycoproteins would give a positive result by forming a purple ring when reacted with alpha-naphthol in concentrated sulfuric acid, due to the presence of carbohydrates in the structure. This is because the test is sensitive to the presence of pentoses, hexoses, and other carbohydrates.
