Modification of Low Molecular Weight Polysaccharides from Tremella Fuciformis and Their Antioxidant Activity in Vitro
In this study, sulfated low molecular-weight Tremella fuciformis polysaccharides (SLTP) with different sulfate contents were synthesized and their antioxidant activities, including superoxide anion radical, 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical and hydroxyl radical scavenging activities were investigated. The results indicated that, compared to natural Tremella fuciformis polysaccharide...
متن کاملInhibition of Oxidative Stress by Low-Molecular-Weight Polysaccharides with Various Functional Groups in Skin Fibroblasts
The aim of this study was to evaluate the in cellulo inhibition of hydrogen-peroxide-induced oxidative stress in skin fibroblasts using different low-molecular-weight polysaccharides (LMPS) prepared from agar (LMAG), chitosan (LMCH) and starch (LMST), which contain various different functional groups (i.e., sulfate, amine, and hydroxyl groups). The following parameters were evaluated: cell viab...
متن کاملResearch Capsule A Guide to Low Molecular Weight GTPases
An increasing number of biological processes have been shown to be regulated by proteins that bind and hydrolyze GTP. The sequence of the presumed active site of GTP hydrolysis is highly conserved in most of these proteins, and, therefore, the three-dimensional structures of these sites are likely to be congruent as well. Homologous structures in the GTPase domains do not, however, indicate a s...
متن کاملMolecular weight and monosaccharide composition of Astragalus polysaccharides.
Two polysaccharides (APS-I and APS-II) were isolated from the water extract of Radix Astragali and purified through ethanol precipitation, deproteination and by ion-exchange and gel-filtration chromatography. Their molecular weight was determined using high performance liquid chromatography and gel permeation chromatography (HPLC-GPC) and their monosaccharide composition was analyzed by TLC and...
متن کاملUltrasonic absorption in aqueous solutions of high-molecular-weight polysaccharides.
The ultrasonic amlfiiLudc absorl)liou coelhcient has Iveen determined in aqueous solutions of four molecular weights (73 000, 186 000, 370 000, and 2 {DO 000) of dextran, a linear • (! --• 6) anhydroglucoae polysaccharide of biological origin, over the frequency range 3-69 Mc/sec at 22øC. It is found that the concentrationfree absorption spectrum exhibits a remarkable similarit)' to that of aqu...
