-
A new neutral polysaccharide (PUP60W-1) was purified from P. umbellatus sclerotia.
-
The first report for a polysaccharide containing many galactoses in P. umbellatus.
-
The main structure of PUP60W-1 was elucidated by methylation analysis and NMR.
-
The chain conformation of PUP60W-1 in water was studied by SEC-MALS-RI-Vis and AFM.
-
Spherical structures of PUP60W-1 were disrupted in water after dispersion with SDS.
