DoLPHiN: A structural and functional database of natural polysaccharides with health benefits

Title Value
Polysaccharide RA
Source Name Portulaca oleracea
Weight 58 kDa
Main Glycosidic Bond(s)
Main Chain RA was found to mainly consist of 1,3-linked Galp (14.5%)、1,3,6-linked Galp (28.4%)、1,6-linked Galp (12.0%) and 1,5-linked Araf (7.8%) 1,3-linked Araf (1.7%) and non-reducing end-residues of Araf (22.3%) and Galp (6.5%), indicating that RA is a typical type II arabinogalactan (AGII) which consists of a 1,3-linked β-D-Galp main chain, partially substituted at C-6 by 1,6-linked β-D-Galp side chains
Side Chain RA was found to mainly consist of 1,3-linked Galp (14.5%)、 1,3,6-linked Galp (28.4%)、 1,6-linked Galp (12.0%) and 1,5-linked Araf (7.8%), 1,3-linked Araf (1.7%) and non-reducing end-residues of Araf (22.3%) and Galp (6.5%), indicating that RA is a typical type II arabinogalactan (AGII) which consists of a 1,3-linked β-D-Galp main chain, partially substituted at C-6 by 1,6-linked β-D-Galp side chains.
