What two aldoses yield D-xylose on Wohl degradation?

Short Answer

Expert verified

Answer

D-iodose and D-gulose are the two aldoses that yield D-xylose on Wohl degradation.

Step by step solution

01

Aldoses

Aldoses can occur in different forms. Some of them include D and L forms.In the Fischer projection, aldoses with alcohol groups located on the right are D-aldoses. L-aldoses constitute aldoses where the alcohol group is situated on the left.

02

Wohl degradation

The Wohl degradation is a procedure that reduces an aldose chain's length. In this process, aldohexose is transformed into aldopentose. The molecule D-glucose can be converted to D-arabinose by Wohl degradation.

03

Aldoses that yield D-xylose on Wohl degradation

The aldoses that produce D-xylose on Wohl degradation are D-iodose and D-gulose. The structure of the aldoses are given as:
