a) Draw Haworth projections of both - and -anomers of D-fructose. Indicate which carbon is the anomeric carbon.b) Sucrose is a disaccharide made up of a molecule of D-fructose and D-glucose. Draw the structure of sucrose clearly indicating the linkage between the two monosaccharides and its biological significance.c) Tollen’s reagent is a very mild oxidizing agent which normally oxidize aldehydes but not ketones. However, both glucose and fructose give positive results with Tollen’s reagent and are classified as reducing sugars. Explain how fructose can also give positive results with Tollen’s reagent (illustrate using structures).

What kind of saccharides are these?

Are digitoxin / digoxin composed of one type or more than one type of monosaccharide? How are the monosaccharide derivatives of digitoxin / digoxin classified (alcohol sugar, deoxy sugar, amino sugar, carboxylic acid sugar)? Are the monosaccharides furanose or pyranose rings?

49. The following compound is a(n) нонно H,N-C-ċ-Ѭċ-ċ-OH H;NCH;CH;CH;CH; H A. monosaccharide B. monopeptide C. disaccharide D. dipeptide E. diglyceride

Classify the following monosaccharides as an aldose or ketose. I need help on number 5, a-d.
