Vedclass · Answer

(D) The $D$ and $L$ configuration of carbohydrates is determined by the configuration of the chiral carbon atom farthest from the carbonyl group,which corresponds to the configuration of $D$-glyceraldehyde or $L$-glyceraldehyde,respectively.$D$ and $L$ designations do not indicate the direction of optical rotation (dextrorotatory or laevorotatory).Optical rotation is determined experimentally and is denoted by $(+)$ for dextrorotatory and $(-)$ for laevorotatory.Therefore,a $D$-carbohydrate can be either dextrorotatory or laevorotatory,and it is not necessarily the mirror image of the corresponding $L$-carbohydrate (which would be its enantiomer,but $D$ and $L$ labels are relative to glyceraldehyde).Thus,none of the given statements are universally true.

$A$ $D$-carbohydrate is:
