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

Title Value
Polysaccharide RN
Source Name Portulaca oleracea
Weight 8.3 kDa
Main Glycosidic Bond(s)
β-Glcp-(1→4)
Main Chain RN was suggested to be an arabinoglucomannan type polysaccharide
Side Chain RN contained 1,4-linked mannopyranosyl (Manp) (34.9%), 1,4-linked glucopyranosyl (Glcp) (22.0%) and 1,2,4-linked Glcp (10.2%) residues with small amounts of 1,4,6-linked Manp (1.9%)、 1,4,6-linked Glcp (0.5%) and terminal-linked galactopyranosyl (Galp) residues (1.8%). In addition, arabinofuranosyl (Araf) residue was suggested to be mainly present as non-reducing terminal linked residues (11.2%).
