WebAmino Acid Racemization. Racemization is the chemical reaction that interconverts an amino acid into its alternative enantiomer or mirror-image form (Fig. 1 ). The rate at which racemization proceeds varies between amino acids according to the ability of R groups to stabilize a carbanion intermediate. Web∎ Racemization takes place in SN1 reaction because in SN1 reaction nucleophile attacks from both sides. ∎ Racemization can be done by mixing to equal quantities of enantiomers ( a pair of molecules that are mirrors of each other). ∎ It converts an optically active compound to an optically inactive compound. Why is SN2 stereospecific?
