ra·ce·mic (r),
(rā-sē'mik, -sem'ik),Denoting a mixture of optically active compounds that is itself optically inactive, being composed of an equal number of dextro- and levorotatory substances, which are separable. Those compounds chracterized by two or more chiral centers and internal compensation (for example, an internal line of symmetry), and are therefore not separable into d or l (or + and -) forms, receive the prefix meso-) (for example, meso-cystine).
