RS configuration of ephedrine

Draw the Haworth projection for the following monosaccharide.

Structures of monosaccharides are a) polymers b) pyranoses or furanoses c) aldoses or ketoses d)  B and C

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).

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?

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

q

Please don't provide handwriting solution

Monosaccharides can be obtained not only from dietary carbohydrates but other major sources include amino acids and glycerol. A) True B) False

two sugars are epimers of each other is it possible to convert one into another without breaking cvalent bond
