- What is the difference between1) an aldose and a ketose ?2) a pentose and a hexose ?3) D- and L-forms of sugars (in Fischer projection)?4) a furanose and a pyranose ? 5) α and ß-forms of sugars (in Haworth projection)?arrow_forward5-Deoxyglucose will close to a?arrow_forwardWhat products are obtained from the reduction of a. d-idose? b. d-sorbose?arrow_forward
- Label each Haworth projection as an α or β anomer and convert the Haworth projection to a sixmembered ring with wedges and dashed wedges.arrow_forwardFor D-lyxose i. Draw an epimer at C3. ii. Draw a diastereomer that is not an epimer. iii. Draw the anomers of -D-lyxofuranose and -D-lyxopyranose. iv. Draw the product as Haworth projection when reacted with methanol catalysed by acid.arrow_forwardAnswer the following questions about the eight aldopentoses: a. Which are enantiomers? b. Which are C-2 epimers? c. Which form an optically active compound when oxidized with nitric acid?arrow_forward
- Draw both pyranose anomers of each aldohexose using a three-dimensional representation with a chair pyranose. Label each anomer as α or β.arrow_forwardDraw the α-d-tagatopyranose sugars using Haworth projections:arrow_forwardAn oligosaccharide isolated from an organism is found tocontain two glucose residues and one galactose residue.Exhaustive methylation followed by hydrolysis producedtwo glucoses with methoxy groups at positions 2, 3,and 6 and galactose with methoxy groups at positions2, 3, 4, and 6. What is the structure of the originaloligosaccharide?arrow_forward
- What D-aldohexose forms the same osazone as D-glucose?arrow_forwardAn aldohexose would have the functional group A. See first image B. See second image C. -CH3 D. more than one choice is correctarrow_forwardIdentify the following as an ? or ? form and draw the Haworth structure of the other anomer.arrow_forward
