Racemates A racemate (or racemic mixture) contains equal quantities of each enantiomer of an optically active compound. ---> they dont show optical activity as the 2 enantiomers cancel each others light-rotating effect
Chemist often react 2 chiral things togetherand get a racemic mixtureof a chiral product. Because when you react 2 molecules there is and equal chance of formin each of the enantiomers.
Pharmaceutical Drugs
Drugs work by changing chemical reactions that happen in the body. Enantiomer has a specific shape to fit to the active site, only one enantiomer with do a certain job.
Possible to use a racemate mixture of the drug to treat a patient. May need to take double the dose to acheive the same effect as the 'pure' enantiomer version.
using a racemic mixture as a drug has benefits : no need to seperate out enantiomers, reducing the difficulty and the cost of producing the drug.
