Abstract

Soluble soybean polysaccharides (SSPS) extracted from soybean cotyledons are acidic polysaccharides, and exhibited a pectin-like structure. After digesting galacturonan with polygalacturonase, two novel galacturonan (GN) fragments, which were directly linked to xylosyl oligosaccharides, were obtained. One consisted of (β-D-Xyl)7 branched at the C-3 site of 1,4-linked (α-D-GalA)4, and the other consisted of (β-D-Xyl)4 branched at the C-3 site of 1,4-linked (α-D-GalA)3.
