- Differentiate Wintrobe from Westergreen regarding the accuracy of the test in a tabulated order. Why do men have lower ESR values than women?If a sample is composed of a mixture of maltose, maltodextrin, and glucose, which of the following is expected? Adding alkaline CuSO4 to the solution will turn the solution into orange with some dark red precipitate. Performing Molisch Test on the sample will give a negative result. Reaction of the sample with phenylhydrazine will give a solution with yellow precipitate. Furthermore, inspection of the precipitate under the microscope will show cotton ball shaped crystals. . The Osazone Test on the sample will give a yellow solution with no visible precipitate.Answer the following: A. Define reducing sugars and their properties B. Among the given tests such as Benedict, Iodine and Reagent Test, which is most highly applicable in biomedical field? Explain.
