Molisch’s test:Molisch’s reagent is added to a diluted sample of monosaccharide and concentrated sulphuric acid is added down the sides of the test tube to form a layer beneath the solution. A purple ring forms at the interface between the layers. Since nucleic acids and glycoproteins also contain monosaccharides, they may react as well.
Selivanov’s test:Selivanov’s test involves acidifying a sugar solution with concentrated hydrochloric acid, adding an ethanolic resorcinol solution and heating. Ketoses react quickly to form a red-coloured dye, while aldoses do not react at all, or only react slowly.
