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 nanoparticle CT contrast agents: in vitro and in vivo studies

open access: yesScience and Technology of Advanced Materials, 2015
Water-soluble and biocompatible D-glucuronic acid coated Na2WO4 and BaCO3 nanoparticles were synthesized for the first time to be used as x-ray computed tomography (CT) contrast agents. Their average particle diameters were 3.2 ± 0.1 and 2.8 ± 0.1 nm for

cDNA Isolation and Functional Characterization of UDP-d-glucuronic Acid 4-Epimerase Family from Ornithogalum caudatum

open access: yesMolecules, 2016
d-Galacturonic acid (GalA) is an important component of GalA-containing polysaccharides in Ornithogalum caudatum. The incorporation of GalA into these polysaccharides from UDP-d-galacturonic acid (UDP-GalA) was reasonably known.

TEMPO oxidation of gelatinized potato starch results in acid resistant blocks of glucuronic acid moieties

open access: yes, 2010
Chemical derivatization is often applied to improve polysaccharide functionality. Primary hydroxyl groups in starch can, for example, be oxidized to aldehydes by using a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated reaction.

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
