WebOct 26, 2024 · When one of the hydrogen atoms is changed to deuterium, this causes the carbon to become a chiral centre. We call this carbon a prochiral carbon. In the same way, the two hydrogens attached to the prochiral carbon is also known as prochiral hydrogens [3]. The prochiral hydrogens can be named pro-R of pro-S based on the resultant … WebCircular dichroism spectroscopy used for the stereochemical characterization of the hydroxylated metabolites formed during the in vitro biotransformation of (R)- and (S)-thalidomide indicated that the chiral center of thalidomide is unaffected by the stereoselective biotransformation process (Meyring et al., 2002). raymond fuller south carolina
