The carbonyl group in d-galactose may be isomerized from C1 to C2 by brief treatmentwith dilute base (by the enediol rearrangement, Section 23-7). The product is the C4epimer of fructose. Draw the furanose structure of the product.
The C2-epimer of D-xylose is called (blank 1). The enediol rearrangementconverts an aldose into a (blank 2). The aldopentose embedded in RNA is(blank 3). An aldopentose would have (blank 4) possible stereoisomers,of whichBlankwould be D-sugars. An ketopentose would have (blank 4) possiblestereoisomers, of which (blank 5) would be D-sugars
An unknown carbohydrate of formula C12H22O11 reacts with Tollens reagent to form asilver mirror. An a@glycosidase has no effect on the carbohydrate, but a b@galactosidasehydrolyzes it to d-galactose and d-mannose. When the carbohydrate is methylated (usingmethyl iodide and silver oxide) and then hydrolyzed with dilute HCl, the products are2,3,4,6-tetra-O-methylgalactose and 2,3,4-tri-O-methylmannose. Propose a structure forthis unknown carbohydrate
