This page provides all possible meanings and translations of the word racemic
containing equal amounts of dextrorotatory (D) and levorotatory (L) stereoisomers and therefore not being optically active; typically, will be synthetic rather than natural
Origin: From racémique, from racemus + -ique or from .
pertaining to, or designating, an acid found in many kinds of grapes. It is also obtained from tartaric acid, with which it is isomeric, and from sugar, gum, etc., by oxidation. It is a sour white crystalline substance, consisting of a combination of dextrorotatory and levorotatory tartaric acids
Origin: [Cf. F. racmique. See Raceme.]
In chemistry, a racemic mixture, or racemate /reɪˈsimeɪt/, is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. A mixture with only a single enantiomer is an enantiomerically pure or enantiopure mixture.
