What is the principle behind the test for unsaturation in lipids?

∙ 15y ago
This test identifies the level of saturation and the number of bonds a oil, fat or lipid has. The more unsaturated, multi-bonded, the lipid is, the more it absorbs iodine. The less iodine it absords, the lipid is considered to be saturated,single bonded.

∙ 9y agoA dilute sol'n of KMnO4 will oxidize an alkene or alkyne. As the unsaturated HC is oxidized the permanganate ion is reduced with the loss of purple color and appearance of brown precipitate of MnO2. Moreover, unsaturated HC can undergo addition due to availability of double bond.

What does bromine in chloroform test for?
unsaturation in a molecule
What is beayers test?
Baeyer's test is a test for multiple bonds within a compound; it is a test of unsaturation.
What does the baeyers test indicate?
It tests for unsaturation. If the substance being tested is saturated, it will not be reactive; but if it is unsaturated there will be a reaction.
Is Ninhydrin used to test for the presence of lipids?
No, a grease spot test or Sudan IV test can be used to test for lipids. Ninhydrin is used to test for amino acids.
What is molybdate test?
molybdate test is a test to detect the presence of phosphate at your solution and the appearance at the lab is purple pink as the phosphate is containing lipids and lipids will react with molybdate test to give pink color. Hope this answer you
What is the principle behind the kraut's test for lipids?
Kraut's test for lipids is a test for glycerol. One of the reagents used in Kraut's test for lipids is bismuth subnitrate

What is the test used to determine the degree of unsaturation?
number of rings
What is the principle behind alkaloidal test?
to find out if the substance is acid or akaline
Does ethyne decolourize KMnO4 solution?
Yes it does. This is a general test for unsaturation.
What is Baeyer test?

Lipids test on brown paper?
If your asking whats the lipids test then it's: Heating a sample with ethanol, if it's cloudy then it contains high levels of lipids.
What is the test used for identifying lipids?
A number of tests are used to test lipids including Suddan III test , emulsion test , solubility test , soapanification test .
Importance of Sudan IV?
Like lipids, the chemical Sudan IV is not soluble in water; it is, however, soluble in lipids. Therefore to test for the presence of lipids in a solution you will use a Sudan IV Test. In this test dark red Sudan IV is added to a solution along with ethanol to dissolve any possible lipids. If lipids are present the Sudan IV will stain them reddish-orange, giving a positive test.
