Can the iodine test distinguish between amylose and amylopectin? What Would you look for? Can sucrose act as a reducing sugar? Explain your answer. In the acid-catalyzed hydrolysis of starch, how can you tell when the hydrolysis of starch is complete? Why does the test work this way? What is the monosaccharide that results at the end? Polysaccharides generally do not give a positive test with Fehling's solution. Why?

actose otum 2) Barfoed's test is used to distinguish monosaccharides from dissacharides. Monosaccharides react with the abdom copper-containing reagent to produce a red copper-containing precipitate. Which of these sugars do you predict will form a red precipitate? 3) Benedict's test can distinguish between reducing sugars and non-reducing sugars. Reducing sugars react with the reagent to produce a yellow, green, or red precipitate. Which sugar(s) used in this experiment do you predict will form a precipitate? 4) Seliwanoff's test distinguishes ketoses...
