racemate

    Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.

racemate

Mixture of equal quantities of two enantiomers, substances whose molecular structures are mirror images of one another (see isomer). The two enantiomers rotate polarized light through opposite angles, canceling each other out so that the racemic mixture has no optical activity. Racemization is the conversion of an optically active form of a compound into a racemic mixture; reversing this process is called resolution.

racemate [′ras·ə‚māt]
(organic chemistry)
An equimolar mixture of the two enantiomers (+ and -, orRandS) of a substance; it is optically inactive.
