Identify the structure of -D-lyxofuranose from the given options.

Step-by-step solution

To identify the structure of -D-lyxofuranose, we need to determine the configuration of D-lyxose and the characteristics of its furanose ring. 1. Structure of D-lyxose: D-lyxose is an aldopentose. In its open-chain Fischer projection, the hydroxyl (-OH) groups at C2 and C3 are on the left side, and the -OH group at C4 is on the right side (which designates it as a D-sugar). 2. Furanose ring formation: A furanose is a 5-membered cyclic hemiacetal. For an aldopentose, this ring is formed by the intramolecular reactio
