Sugar, amino acid and inorganic ion profiling of the honeydew from different hemipteran species feeding on Abies alba and Picea abies.

open access: yesPLoS ONE, 2020
Several hemipteran species feed on the phloem sap of plants and produce large amounts of honeydew that is collected by bees to produce honeydew honey. Therefore, it is important to know whether it is predominantly the hemipteran species or the host plant

Structural analysis of three novel trisaccharides isolated from the fermented beverage of plant extracts

open access: yesChemistry Central Journal, 2009
Background A fermented beverage of plant extracts was prepared from about fifty kinds of vegetables and fruits. Natural fermentation was carried out mainly by lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp. and Pichia spp.).

A new trisaccharide derivative from Prenanthes purpurea - SHORT COMMUNICATION [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
A methanolic extract of Prenanthes purpurea L. leaves yielded 1,6”-di-O-cinnamoyl-β-D-glucopyranosyl-(1®3)-O-α-L-rhamnopyranosyl-(1®6)-O-β-D-glucopyranoside. The NMR and physical data of this new natural compound are reported.

Purification and Characterization of a Novel Alginate Lyase from the Marine Bacterium Bacillus sp. Alg07

open access: yesMarine Drugs, 2018
Alginate oligosaccharides with different bioactivities can be prepared through the specific degradation of alginate by alginate lyases. Therefore, alginate lyases that can be used to degrade alginate under mild conditions have recently attracted public ...

Biochemical analysis of cross‐feeding behaviour between two common gut commensals when cultivated on plant‐derived arabinogalactan

open access: yesMicrobial Biotechnology, 2020
Summary In this paper, we reveal and characterize cross‐feeding behaviour between the common gut commensal Bacteroides cellulosilyticus (Baccell) and certain bifidobacterial strains, including Bifidobacterium breve UCC2003, when grown on a medium ...

Enzymatic acylation of di- and trisaccharides with fatty acids: choosing the appropriate enzyme, support and solvent [PDF]

open access: yes, 2002
Enzymatic synthesis of fatty acid esters of di- and trisaccharides is limited by the fact that most biological catalysts are inactivated by the polar solvents (e.g. dimethylsulfoxide, dimethylformamide) where these carbohydrates are soluble. This article

Synthesis of Oligosaccharide Libraries Through Glycosylations on Unprotected Acceptors

open access: yesNatural Product Communications, 2019
Starting from an unprotected GlcNAc acceptor, after first random glycosylation and deprotection, and second random glycosylation, deprotection, and purification, we were able to obtain a trisaccharide library containing 36 α-linked trisaccharide library.

Design and Synthesis of 1-O- and 6′-C-Modified Heparan Sulfate Trisaccharides as Human Endo-6-O-Sulfatase 1 Inhibitors

open access: yesFrontiers in Chemistry, 2022
The extracellular human endo-6-O-sulfatases (Sulf-1 and Sulf-2) are responsible for the endolytic cleavage of the 6-sulfate groups from the internal D-glucosamine residues in the highly sulfated subdomains of heparan sulfate proteoglycans.
