Although a court must not declare that a prima facie case of obviousness exists for an enantiomer over its prior art racemate in the absence of the Graham factual inquiries, (132) the structural similarities between a single enantiomer and its racemate are usually sufficient to establish a prima facie case.

Because it's difficult to predict just how a racemate will affect people, pests, or the environment, most chemists would prefer to avoid such mixtures.

MDMA is a chiral compound used as a racemate, and an examination of the pharmacological activity of the individual enantiomers indicates that the (+)-S-enantiomer is more active in terms of "the degree and the disruptiveness of the induced intoxication" (12) than the (-)-R-enantiomer.

Researchers from the Iowa State University study compared the pharmacokinetics of L-theanine, D-theanine and an ingredient commercially marketed as L-theanine that actually was a racemic mixture of theanine, a 50:50 D- and L-theanine mixture, also known as racemate.
