Question

Name the following aldoses. (Include in the names the stereochemical designation D or L and, where appropriate, the configuration of the anomeric carbon, alpha or beta. This question is case-sensitive, so capitalize only the D or L.) ball & stick + labels ball & stick labels

PLEASE NAME!! OWL is VERY specific on the names. I have very limited attempts for this question. All of these pictures are the same two molecules. Letter A in the last picture corresponds to the first structure in the first two pics, etc.. I have drawn out what the fischer and haworth projections would look like for the molecules in question. please indicate D and L as well as alpha/beta (for the second structure). Thank you!

Answer 1

I am answering it according to the configuration you have drawn.

a) D-ribose

b) beta-D-ribofuranose (using symbol of beta)

CHO он H oH HP -on си, он D- saldobentose if your configuration is correct, then it is D-Libose Hoc a oh NHH/H ß-D- ribofuromose OH OH Explanation :- CHOH HHOH TOH Cu oH - L Coh on left side) COH on Right side). to assign Dorl see the bottom of position as shown above urrespective of other H, OH or groups. to assign x or ß anomer :- a on Anomere a 4 A Anomere carbon. You - since ß-form the Anomeric X-form. is on part right of the Ring Page No.
