What is the significance of seliwanoff's test?
Seliwanoff's test is used to distinguish between ketoses and aldoses in carbohydrates. It is based on the reaction of ketoses with resorcinol in concentrated acid to produce a cherry-red color, while aldoses do not give this color change. This test is particularly useful in differentiating fructose (a ketose) from glucose (an aldose).
Why seliwanoff's test is positive only for keto sugars?
Ketose reacts more readily with seliwanoff's test because:= ==Ketones have 3 carbon atoms where Aldehyde has 2 hydrogen atoms and one carbon atoms.=
