raceminen
Raceminen, or racemate, is a chemical term for a mixture that contains equal amounts of the two enantiomers of a chiral molecule. Each enantiomer is a non-superimposable mirror image of the other, and while they share the same chemical formula and connectivity, they may have different three-dimensional shapes and biological activities. A racemic mixture is optically inactive because the clockwise and counterclockwise rotations cancel each other.
Raceminen can form through non-selective synthesis, racemization under certain conditions, or partial resolution where one enantiomer
Analytical and separation techniques include polarimetry, circular dichroism, and chiral chromatography or synthesis. In many cases,
Examples: Many drugs have been marketed as racemates; thalidomide is a well-known case illustrating enantiomer-specific effects.
Raceminen remains a central concept in stereochemistry, influencing drug development, flavor and fragrance chemistry, and materials
