资源简介：
aValues are expressed in ppm. The hexose residues were labeled A to G in order of increasing chemical shift of their anomeric protons. B and B’ branching point units were differentiated on the basis of their H-6 and C-6 chemical shifts. Values of the free C-6 for units A, C and D are 60.65, 60.54 and 60.12 ppm.
