A polysaccharide YCP was prepared from a marine filamentous fungus Keissleriella sp. YS4108, which exhibited as a molecular weight (Mw) of 2.4x10(3) kDa and its three sulfated derivatives (YCP-SL, YCP-SM and YCP-SH) were synthesized, the degree of substitution (DS) of

In this study, three chemically sulfated polysaccharides (SPAPs) were derived from one water-soluble polysaccharide (PAP) of Polyporus albicans mycelia by chlorosulfonic acid-pyridine method. The effects of polysaccharides on the immune function were examined after the mice were intragastrical administrated with

We report that chlorosulfonic acid is a true solvent for a wide range of carbon nanotubes (CNTs), including single-walled (SWNTs), double-walled (DWNTs), multiwalled carbon nanotubes (MWNTs), and CNTs hundreds of micrometers long. The CNTs dissolve as individuals at low concentrations
