WebThe process by which an L-amino acid changes into a mixture of the L- and D-forms (or the D-form changes into a mixture of the L- and D-forms) is called racemization. Racemization is complete when equal amounts of the L- and D-forms are obtained. WebRacemization is an obvious way to recycle the unwanted enantiomer. It would be particularly advantageous to do this in situ. The opportunities for racemization depend on the structure and chemistry of the compound; there are no generic approaches. come leggere codice windows 10
