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 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.
What does a positive Molisch's test on an unknown substance indicate?
A positive Molisch's test result indicates 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.
Will a deoxy ribonucleic acid give a positive molisch test?
No, deoxyribonucleic acid (DNA) will not give a positive Molisch test. The Molisch test is a carbohydrate test that detects the presence of sugars, which are polysaccharides or monosaccharides. Since DNA is a nucleic acid composed of nucleotides, not carbohydrates, it does not react positively in this test.
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.
Does coconut oil give positive result on molisch test?
Coconut oil typically does not give a positive result in the Molisch test, as this test is designed to detect the presence of carbohydrates, particularly sugars. Coconut oil is primarily composed of fats and does not contain significant amounts of carbohydrates. Therefore, it generally does not react with the reagents used in the Molisch test.
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.
