d) Consider the following disaccharide C. i. ii. iii. iv. OH HO OH OH HO Disaccharide C OH OH OH Give the IUPAC name for disaccharide C. What is the type of glycosidic linkage. Is disaccharide C a reducing sugar? Does it mutarotate? Explain your answer. What products are formed when disaccharide C is hydrolysed with H3O+.
A)Label each sugar as D or L b. Label each sugar as a or B
Although the first two carbons of fructose and glucose are identical in structure to DHAP and GADP (from glycolysis), DHAP and GADP equilibriate on their in solution to favor the ketone over the aldehyde, while fructose and glucose do not. Why? a)The larger size of the molecule sterically hinders the isomerization b)The larger sugars have more OH groups which hydrogen bond and disrupt isomerization c)The larger sugars cyclize, and there is no carbonyl to isomerize in the cyclic form d)The larger sugars cyclize, and in the cyclic form the hydrogen bonding is very strong e)The larger sugars are less soluble in water than the smaller sugars
Write the reaction equation for the formation of sucrose, indicate the bonds that connect the monosaccharides in the disaccharide. Biological value of sucrose.
What are the monosaccharides in the picture and the type of glycosidic bond of the disaccharide?
The structure below shows that of a trisaccharide that is composed of (going from top left to bottom right) galactose, glucose, and fructose. More specifically, the component monosaccharides are [D-galactose, L-galactose], [D-glucose, L-glucose], and [D-fructose, L-fructose] .
2) Consider the following disaccharide which was formed from the breakdown of a polysaccharide found in plant material. ОН Glycosidic linkage: H H OH H H НО H H. OH H. ОН OH H НО H ОН a. Label the glycosidic linkage above in the following format: a/B(# → #) b. Would you expect this disaccharide to have been formed from amylose or amylopectin? c. Describe at least two chemical tests that would give insight into the structure of this disaccharide, assuming you've isolated it and wanted to elucidate the structure from scratch. Include detail on not only the tests you would use but what results you would expect to get given the structure above. Assume you can analyze the structure of any monosaccharide you get from your chemical tests.
