Vedclass · Answer

(B) $L$-arabinose is an aldopentose with the configuration $(2S, 3S, 4S)$ in its open-chain form. In the Fischer projection,for an $L$-sugar,the hydroxyl group $(-OH)$ on the chiral carbon furthest from the aldehyde group (the $C-4$ carbon in this case) must be on the left side. Comparing the given structures: - Structure $A$ represents $D$-xylose. - Structure $B$ represents $L$-arabinose,as the $-OH$ group at $C-4$ is on the left,and the configuration matches the $L$-arabinose stereoisomer. - Structure $C$ represents $D$-ribose. - Structure $D$ represents $D$-glucose (an aldohexose). Therefore,the correct structure is $B$.

Which of the following structures is $L$-arabinose?
