Studies on Medicago lupulina saponins. 5. Isolation and chemical characterization of blossom saponins

open access: yesActa Societatis Botanicorum Poloniae, 2014
The separation of saponins derived from Medicago lupulina L. flowers yielded two saponin fractions. The first one, made up of crystalline saponins, readily precipitable from water solution, was a mixture of three glycosides of soyasapogenol B.

Synthesis of Glycosides of Glucuronic, Galacturonic and Mannuronic Acids: An Overview

open access: yesMolecules, 2011
Uronic acids are carbohydrates present in relevant biologically active compounds. Most of the latter are glycosides or oligosaccharides linked by their anomeric carbon, so their synthesis requires glycoside-bond formation. The activation of this anomeric

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.
