Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine
