Structural characterization of an α-glucan from Dendrobium officinale and its gut microbiota-dependent protective effects against DSS-induced ulcerative colitis in mice
{{output}}
A homogeneous polysaccharide, DOP-W-1, was isolated from Dendrobium officinale and identified as a low-molecular-weight branched α-glucan with a molecular weight of 9.76 kDa, mainly consisting of →4)-α-D-Glcp-(1 → and →4,6)-α-D-Glcp-(1 → residues. This ... ...
