racemizálást
Racemization is a process in stereochemistry where a chiral compound, which exists as a pair of enantiomers, is converted into an equal mixture of these enantiomers. Enantiomers are stereoisomers that are non-superimposable mirror images of each other. A 50:50 mixture of two enantiomers is called a racemic mixture or a racemate.
Racemization typically occurs when a chiral center, usually a carbon atom bonded to four different groups,
Racemic mixtures are optically inactive because the rotation of plane-polarized light by one enantiomer is exactly
