Vedclass · Answer

(A) For a monosaccharide to be correlated to $D$-glyceraldehyde,the $-OH$ group on the lowest chiral carbon (the chiral carbon farthest from the carbonyl group) must be on the right-hand side in the Fischer projection.Looking at the structures provided in the solution image:In structure $(A)$,the $-OH$ group on the lowest chiral carbon is on the right.In structure $(B)$,the $-OH$ group on the lowest chiral carbon is on the right.In structure $(C)$,the $-OH$ group on the lowest chiral carbon is on the left ($L$-configuration).In structure $(D)$,the $-OH$ group on the lowest chiral carbon is on the right.Thus,structures $(A)$,$(B)$,and $(D)$ have the $D$-configuration.The total number of such structures is $3$.

List-$I$ $(\text{Saccharides})$	List-$II$ $(\text{Glycosidic linkages found})$
$(A)$ Sucrose	$(I)$ $\alpha 1-4$
$(B)$ Maltose	$(II)$ $\alpha 1-4$ and $\alpha 1-6$
$(C)$ Lactose	$(III)$ $\alpha 1-\beta 2$
$(D)$ Amylopectin	$(IV)$ $\beta 1-4$

Identify the number of structures from the following which can be correlated to $D$-glyceraldehyde.
