LEVOGYRATE
Le`vo*gy"rate, a. Etym: [Levo- + gyrate.] (Chem. & Physics)
Defn: Turning or twisting the plane of polarization towards the left, as levulose, levotartaric acid, etc. [Written also lævogyrate.]
LEVOROTATION
Le`vo*ro*ta"tion, n. [Written also lævorotation.] [Levo- + rotation.]
(Physics & Chem.)
Defn: Rotation in the direction of an outgoing right-handed screw; counter-clockwise rotation; — applied chiefly to the turning of the plane of polarization of light.

LEVULIN
Lev"u*lin, n. (Chem.)
Defn: A substance resembling dextrin, obtained from the bulbs of the dahlia, the artichoke, and other sources, as a colorless, spongy, amorphous material. It is so called because by decomposition it yields levulose. [Written also lævulin.]
