- 論文の詳細を見る
The nuclear magnetic resonance spectra of anomeric pairs of acetylated D-gluco-pyranosylglucopyranoses and 1→4 and 1→6 linked D-glucans were measured in deuteriochloroform at 60 or 100 MHz. The spectral pattern difference between anomers, due to the 1,3-diaxial deshielding effect in α-anomer, proved to be an useful means to assign the configuration of glucosidic linkage. Low and high field shifts of acetoxy signals were observed in some acetylated D-glucans.
