Circularly polarized x-rays probe crystal chirality
- 1. RIKEN, SPring-8 Center, Sayo, Hyogo (Japan)
Description
Enantiomers in many proteins, sugars and pharmaceuticals crystallize into two forms that are mirror images of each other like our right and left hands. X-rays, which are normally useful in determining the structure of materials and biomolecules, are much less sensitive to the 'handedness' of an enantiomer. We have shown that right and left circularly polarised (RCP and LCP) X-rays at the resonant energy can distinguish 'left' from 'right' low-quartz, whose crystal structures are mirror images of each other.
