WHAT DOES LEVOROTARY MEAN IN ENGLISH?
Dextrorotation and levorotation
Dextrorotation and levorotation refer to the properties of rotating plane polarized light. If the light rotates clockwise as it approaches an observer, this is known as dextrorotation, light with a rotation to the right. If the light rotates counterclockwise as it approaches the observer, then the light exhibits levorotation, rotation to the left. A compound with dextrorotation is called dextrorotatory or dextrorotary, while a compound with levorotation is called levorotatory or levorotary. Compounds with these properties are said to have optical activity and consist of chiral molecules. If a chiral molecule is dextrorotary, its enantiomer will be levorotary, and vice-versa. In fact, the enantiomers will rotate plane polarized light the same number of degrees, but in opposite directions. Apart from direct measurement of the optical rotation of an actual sample, it is only possible to determine whether a given chiral molecule will be levorotatory or dextrorotatory, directly from its absolute configuration, via detailed computer modeling. That is to say, both "R" and "S" stereocenters have the ability to be dextrorotatory or levorotatory.

Food Carbohydrate Chemistry
Thus, being a D- or L-sugar does not predict whether a sugar is dextrorotary or
levorotary. The designation D and L should not be confused with d and l, which
denotes having optical activity that is dextrorotary or levorotary. (The trivial names

Chestnut's Obstetric Anesthesia: Principles and Practice
The direction inwhichthe isomers rotate polarized light distinguishes them as
either dextrorotary (D) or levorotary(L) isomers. This distinction is important,
because individual isomers of thesamedrug may havedifferent biologic effects.
