D-

In biochemistry, a symbol used as a prefix to indicate the spatial configuration of certain organic compounds with asymmetric carbon atoms. It is used if an organic compound has a configuration about an asymmetric carbon atom analogous to that of D-glyceraldehyde (the arbitrarily chosen standard), in which the hydroxy (OH) functional group is on the right side of the asymmetric carbon atom.

[From DEXTROROTATORY.]

pref.

Relating to the configuration of D-glyceraldehyde, a compound chosen as the basis for stereochemical nomenclature because it is the simplest carbohydrate that can form optical isomers: D-fructose.
