Answer

Furanose anomers of D-Erythrose

Step by step solution

01

D-erythrose

The compound D-erythrose has the molecular formula C₄H₈O₄. It acts as a plant metabolite and is also present in animal cells.The structure of D-erythrose is as shown:

D-erythrose

02

Furanose Ring

The ring with four carbons and one oxygen atom is a furanose ring; thus, furanose is a five-membered ring, and D-erythrose usually exists in furanose form.

03

Anomers of D-erythrose

The compound D-erythrose exists in two anomeric forms, which differ in the configuration at the first carbon.
