Dependency of the regio- and stereoselectivity of intramolecular, ring-closing glycosylations upon the ring size

open access: yesBeilstein Journal of Organic Chemistry, 2011
Phenyl 3,4,6-tri-O-benzyl-2-O-(3-carboxypropionyl)-1-thio-β-D-galactopyranoside (1) was condensed via its pentafluorophenyl ester 2 with 5-aminopentyl (4a), 4-aminobutyl (4b), 3-aminopropyl (4c) and 2-aminoethyl 4,6-O-benzylidene-β-D-glucopyranoside (4d),

Indium-mediated C-allylation of melibiose

open access: yesBeilstein Journal of Organic Chemistry, 2019
The indium-mediated allylation reaction has been applied to melibiose, a disaccharidic substrate. This elongation methodology allows for a short, efficient and diastereoselective approach towards complex glycosylated carbohydrate structures.

Hydroxymethyl Rotamer Populations in Disaccharides.

open access: yesChemInform, 2003
Sixteen methyl glucopyranosyl glucopyranoside disaccharides (methyl beta-d-Glcp(p-Br-Bz)-(1-->x)-beta/alpha-d-Glcp) containing beta-glycosidic linkages (1-->2, 1-->3, 1-->4, and 1-->6) were synthesized and analyzed by means of CD and NMR spectroscopy in three different solvents.

Synthesis and Reactivity of 4′-Deoxypentenosyl Disaccharides

open access: yesJournal of Organic Chemistry, 2014
4-Deoxypentenosides (4-DPs) are versatile synthons for rare or higher-order pyranosides, and they provide an entry for structural diversification at the C5 position.

On-slide tissue digestion for mass spectrometry based glycomic and proteomic profiling

open access: yesMethodsX, 2019
We describe a protocol for glycomic and proteomic profiling that uses serial enzyme digestions from the surface of fresh frozen or fixed tissue slides. The abundances of the extracted glycans and peptides are determined using liquid chromatography-mass ...

Synergistic Antioxidant Activity between Honey and Phenolic Compounds

open access: yesProceedings, 2020
Honey is a natural product that has the characteristics of a deep eutectic natural solvent (NADES) due to the intermolecular interactions between monosaccharides and disaccharides, especially the hydrogen bonds formed between them. [...]

Cereal non-starch polysaccharides in pig diets [PDF]

open access: yes, 2003
This thesis is based on three different studies comprising the weaning and the growing period, aiming at monitoring the influence of cereal non-starch polysaccharides (NSP) and dietary enzyme supplementation on gastro-intestinal processes in pigs.

Chromatographic Separation of Isomaltooligosaccharides on Ion-Exchange Resins: Effect of the Cationic Form

open access: yesAdsorption Science & Technology, 2012
Prebiotic isomaltooligosaccharides (IMOs) are composed of α-d-glucose units linked by glucosidic α (1Ø6) bonds and they remain intact until reaching the large bowels, where they are metabolized by bifidobacteria and lactobacillus.
