Uplоаd аn imаge оf yоur answers to this question. Splenda is a sugar substitute that can be used in cooking, whereas Nutrasweet cannot (it is a dipeptide and is thermally unstable). Splenda is made from D-sucrose by substitution of some of the hydroxyl groups with chlorine atoms. Draw the structure of Splenda given the following information about how it differs from sucrose. The hydroxyl groups at carbons 1 and 6 of the sugar in the furanose form and the hydroxyl group at carbon 4 of the sugar in the pyranose form have been replaced by chlorine atoms. Additionally, the sugar in the pyranose form has the same stereochemical configuration as galactose. For your interest: A foreign post-doctoral student in Great Britain first prepared Splenda. He misunderstood the word “test” and thought the supervisor said “taste,” so he did (not good chemical practice). It turned out that this chlorinated derivative of sucrose is 600 times sweeter than sucrose itself.
