A vacuum-ultraviolet circular-dichroism spectroscopy using synchrotron radiation greatly expands the utility of chiroptical technique for the structural analysis of biomolecules by combining with theoretical analysis and bioinformatics. This spectroscopy provides the structural dynamics, intramolecular hydrogen bonds, and hydrations of saccharides, and also successfully estimates the secondary structure contents, numbers of segments, and sequences of native proteins and non-native proteins such as membrane-bound proteins. The circular dichroism theory of protein discloses the local structures of the amyloid fibrils at the molecular level. This synchrotron-radiation spectroscopy is opening a new filed in the glycobiology and structural biology.
