Racemic mixture. A racemic mixture or racemate in chemistry is one that has equal amounts of left-and right-handed enantiomers of a chiral molecule.The first known racemic mixture, or racemate, was ' racemic acid ', which Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid.ome drug molecules are chiral and the enantiomers have different effects on biological entities. They can be sold as one enantiomer or as a racemic mixture. Examples include Thalidomide, Ibuprofen, and Salbutamol. Ritalin is a mixture of several different enantiomers.
