N.m.r. studies of the disulphated disaccharide obtained by degradation of bovine lung heparin with nitrous acid

T N Huckerby et al. Carbohydr Res. .

Abstract

The disulphated disaccharide IdoA(2SO3)-anManOH(6SO3) was prepared from bovine lung heparin by treatment with nitrous acid followed by borohydride reduction. The 1H- (400 MHz) and 13C-n.m.r. (100 MHz) spectra of this disaccharide derivative have been assigned completely using homonuclear spin-decoupling experiments, 13C-1H correlations, and a COSY-45 two-dimensional homonuclear correlation experiment. The 3JH,H values show that the IdoA(2SO3) residue exists in a single conformation throughout the temperature range 20-90 degrees.
