Racemization of thalidomide
In general, most biochemical reactions are stereoselective, so only one stereoisomer will produce the intended product while the other simply does not participate or can cause side-effects. 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. Also notable is th… WebApr 22, 1994 · DOI: 10.1016/0021-9673(94)80385-4 Corpus ID: 94864704; Investigations on the in vitro racemization of thalidomide by high-performance liquid chromatography …
