What Is an Enantiomer?

Enantiomers (enantiomers) are enantiomers, which are optically active, one of which is left-handed and the other is right Enantiomers are also called optical isomers.

Marus discovered in 1808

Enantiomers have the same physical properties (such as melting point, boiling point, solubility, refractive index, acidity, density, etc.),

tartaric acid

Most compounds containing one or more asymmetric carbon atoms behave as enantiomers, but this is not always the case. There are several known compounds with asymmetric carbon atoms, but they are asymmetric with respect to the entire molecule and do not exhibit enantiomers. For example, tartaric acid has two asymmetric carbon atoms, but since the two halves of the molecule are equal and opposite to each other, they can overlap on their geometric mirror images, so the sample still exhibits optical inactivity.

There are three types of lactic acid depending on the source. One is lactic acid obtained from animal muscles, which is D-body; the other is lactic acid obtained by fermentation, which is L-body; the third is artificially synthesized, which is external Racemate. There is an asymmetric carbon atom in the molecule, which is optically active, so there are two optical isomers, L-lactic acid and D-lactic acid.
