WebOct 30, 2014 · The racemization of thalidomide is well studied by us and others (ref. 3 and 12d–g); however, a possibility of the SDE effect on the racemization rate of thalidomide is never concerned. Generally, racemization is one of many chemical reactions, the rate of which depends on the species concentration. WebAmir-Hossain Parham is an academic researcher from University of Bonn.

Of note, the L form of amino acids and the D form of sugars (primarily glucose) are usually the biologically reactive form. This is due to the fact that many biological molecules are chiral and thus the reactions between specific enantiomers produce pure stereoisomers.
