- Create an illustrated step-by-step schematic diagram of the following Analysis of Lipids: Huble's testBoth reducing monosaccharide and disaccharide give positive results in Barfoed's test. Which of the following indicators would you be able to distinguish the two?* A. Monosaccharides will react more slowly than disaccharide. B. Disaccharides are easily oxidized than monosaccharide, thus gives red precipitate more quickly than monosaccharide. C. Monosaccharide is more reactive thus gives red precipitate later than disaccharide D. Disaccharide undergoes hydrolysis first, thus takes more time to form red precipitate than monosaccharide.Answer questions 4, 5, and 74.
