Figuring Out the Configuration

George PrestonPeptides can sometimes exhibit unusual stereochemistry.  Occasionally, for example, the usual l-amino acid building block might be substituted with its mirror-image counterpart. Such features can impact on function, but may be subtle enough to evade detection via routine methods. In this article, I highlight some innovative mass-spectrometry-based approaches to the characterisation of peptides with exotic stereochemical features.
