Sugar molecules adsorbed at hydrated inorganic oxide surfaces occur ubiquitously in nature and in technologically important materials and processes, including marine biomineralization, cement hydration, corrosion inhibition, bioadhesion, and bone resorption. Among these examples, surprisingly diverse hydration behaviors are observed for oxides in the presence of saccharides with closely related...

Salvia miltiorrhiza is a traditional Chinese herbal medicine containing multiple components that contribute to its notable bioactivities. This article investigated the distribution and dynamic changes of chemical constituents in various parts of S. miltiorrhiza from different growth periods. An ultra-high performance liquid chromatography-triple quadrupole mass spectrometer (UPLC-TQ-MS/MS) and ...

Glucose, maltodextrin, and sucrose exhibit significant differences in their alkaline reaction properties and interactions in aluminate/silicate cement slurries that result in diverse hydration behaviors of cements. Using 1D solution- and solid-state (13)C nuclear magnetic resonance (NMR), the structures of these closely related saccharides are identified in aqueous cement slurry solutions and a...

Yacon is a perennial plant originating from the Andean region whose roots have been receiving increased attention due to their high content of prebiotic fructooligosaccharides (FOS). Apart from many health benefits, FOS have interesting characteristics as food ingredients, so are used as sugar substitute, and their extraction from yacon roots may be an alternative to commercially available FOS....

A method for separating the outer and inner membranes of Pseudomonas aeruginosa PAO1 in the absence of added ethylenediaminetetraacetic acid was devised. The method yields two outer membrane fractions which show the same protein pattern on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, but differ substantially in their relative contents of phospholipids. One of these outer membrane ...

Signalling by fibroblast growth factors (FGFs) through FGF receptors (FGFRs) depends on the cell-surface polysaccharide heparan sulphate (HS) [1] [2]. HS has an ordered domain structure of highly diverse saccharide motifs that present unique displays of sulphate, carboxyl and hydroxyl groups [3]. These motifs interact with many proteins, particularly growth factors. HS binds both to FGFs [4] [5...

Calcium alginate membrane has great potential for membrane separation technology. The polymer frameworks of the membrane were successfully regulated by the mass fraction of homopolymeric blocks of -L-guluronic acid (FGG) in the entire molecular chain of alginate and the additive CaCl2 as a cross-linker. The mechanical strength can be controlled by regulated the FGG and CaCl2 concentration. Sele...

We report a saccharide recognition system by modifying responsive copolymers on the solid-based multiple nanochannels. The ion transport through nanochannels can be regulated by ultra-low concentration of saccharides, which can switch nanochannels between the "on" and "off" states.

A Pd-based indicator displacement assay for the fluorimetric sensing of carbohydrates has been developed. The assay allows the detection of saccharides in the low millimolar concentration range in water at neutral pH.

A combinatorial ionic-liquid-supported "catch-and-release" strategy for oligosaccharide synthesis (combi-ICROS) is reported. A series of β-(1→6) glucan di-, tri- and tetra-saccharides were synthesized in one pot to showcase the versatility of the strategy.
