Automated solid phase synthesis enables rapid access to the linear and branched arabinofuranoside oligosaccharides. A simple purification step is sufficient to provide the conjugation ready oligosaccharides in good yield.

• S. obliquus was effectively fractionated by mild (un)catalyzed hydrothermal processes. Soluble sugars were mainly present as soluble oligosaccharides. Protein retained in the solid fraction. Dilute acid hydrolysis allowed higher oligosaccharides yield at conditions. Co-production of added-value marine biorefineries. Scenedesmus , a biotechnologically recognized microalga, grown 70 L vertical ...

The incorporation of functional ingredients, such as prebiotics and probiotics in food matrices, became a common practice the human diet to improve nutritional value product itself. Worldwide, skim milk (SKM) is one most consumed comprising all essential nutrients desired for balanced diet. Thus, modulation gut microbiota by SKM supplemented with different well-known ingredients was evaluated. ...

Many nutrition scientists are not yet aware that human milk contains significant quantities of carbohydrates other than lactose. If you’ve never heard of lacto-N-tetraose or sialyllactose, you are not alone. The role of oligosaccharides in other fields has attracted widespread excitement but curiously little interest has been shown in the oligosaccharides of human milk. Many of the 130 differen...

Hemicellulose in corncob was simultaneously degraded and oxidized into oligosaccharides, which served as a masking agent for leather tanning.

Marine oligosaccharides have attracted increasing attention recently in developing potential drugs and biomaterials for their particular physical and chemical properties. However, the composition and sequence analysis of marine oligosaccharides are very challenging for their structural complexity and heterogeneity. Mass spectrometry (MS) has become an important technique for carbohydrate analys...

A purified feruloyl esterase (EC 3.1.1.73) from Aspergillus nidulans produced in Pichia pastoris was used to study the de-esterification of large feruloyl oligosaccharides consisting of 4 to 20 pentose residues and (xylose plus arabinose) and one ferulic acid residue. The feruloyl oligosaccharides were prepared from total oligosaccharidic hydrolysates from wheat bran treated with a purified end...

Automated glycan assembly (AGA) has advanced from a concept to a commercial technology that rapidly provides access to diverse oligosaccharide chains as long as 30-mers. To date, AGA was mainly employed to incorporate trans-glycosidic linkages, where C2 participating protecting groups ensure stereoselective couplings. Stereocontrol during the installation of cis-glycosidic linkages cannot rely ...

Inhibition of immune precipitation with oligosaccharides obtained from Candida stellatoidea mannan has been used to provide more information about the haptenic groups of this serologically active polysaccharide. The oligosaccharides di-, tri-, tetra-, and a mixture of penta- and hexasaccharides were studied. The inhibitory activity of these materials was tested with two immune sera. With one se...

We explored the application of electron detachment dissociation (EDD) and infrared multiphoton dissociation (IRMPD) tandem mass spectrometry to fluorescently labeled sialylated oligosaccharides. Standard sialylated oligosaccharides and a sialylated N-linked glycan released from human transferrin were investigated. EDD yielded extensive glycosidic cleavages and cross-ring cleavages in all cases ...
