Examples
For example, racemic amphetamine can be treated with d- tartaric acid to form a diastereoisomeric salt which is fractionally crystallized to yield dextroamphetamine.
In the example shown below, the meso form of tartaric acid forms a diastereomeric pair with both levo and dextro tartaric acids, which form an enantiomeric pair.
The mystery was that tartaric acid derived by chemical synthesis had no such effect, even though its chemical reactions were identical and its elemental composition was the same.
Winemakers can counteract this by adding tartaric acid in a process known as "acidification".
