‘Hexuronic Acid”(Ascorbic Acid) as the Antiscorbutic Factor [PDF]

Nature, 1933
IN view of the facts that (1) hexuronic acid is the name of a class of substances rather than that of one individual compound, and that (2) the material described as hexuronic acid isolated from adrenal cortex and now from Paprika contains a molecule of water less than is required for a hexuronic acid, we wish to ascribe the name ascorbic acid to the ...

The Absorption Spectrum of Hexuronic Acid [PDF]

Nature, 1932
As part of a systematic study1 of Prof. Szent-Gyorgyi's ‘hexuronic acid’ we have investigated quantitatively the absorption spectra of hexuronic acid, glycuronic acid, galacturonic acid, tetramethyl I³-fructose, and other carbohydrate derivatives.

Monoacetone Hexuronic Acid [PDF]

Nature, 1932
TWENTY grams of hexuronic acid, prepared by Svirbely and Szent-Gyorgyi, were shaken in 500 c.c. of acetone in the presence of 50 grams of anhydrous copper sulphate for twenty-four hours. After filtration, the fluid was evaporated in vacuo to one third of its volume.

Extraction and Optimization of Fucoidan From Sargassum muticum Using Acidic Eutectic Solvents and Evaluation of Their Effects on Fibroblast Cell Lines. [PDF]

ChemistryOpen
Fucoidan, a sulfated polysaccharide extracted from the cell wall of macroalgae such as S. muticum, exhibits promising biological properties. This study investigated a green extraction using deep eutectic solvents (DESs), with an emphasis on process optimization and bioactive evaluation of fucoidan.

Erucastrum virgatum subsp. virgatum (Brassicaceae) Endemic to Sicily (Italy): Biological Properties and Phenolic Content of Leaf Extracts. [PDF]

Chem Biodivers
ABSTRACT The present work reports a comparative study between extracts obtained by different methods (ultrasonic bath‐assisted extraction, maceration, decoction, and Soxhlet extraction) from the leaves of Erucastrum virgatum subsp. virgatum collected in Sicily (Italy), using ethanol and water as “green” solvents.

Improving in vitro Gastrointestinal Stability of Phlorotannins From Food Grade Fucus vesiculosus Extracts Using Cyclodextrins. [PDF]

J Food Sci
ABSTRACT Phlorotannins have gained significant attention for their potential bioactive and functional properties. However, these compounds are highly sensitive to gastrointestinal digestion, which limits their bioavailability and consequently the in vivo efficacy.

Glycosaminoglycans as Polyelectrolytes: Charge, Interactions, and Applications. [PDF]

Chembiochem
Glycosaminoglycans (GAGs) are linear, anionic biopolymers with their functions tightly linked to their charge. This review approaches GAGs from a polyelectrolyte perspective, shedding light on how the distribution of sulfate groups and, thus, negative charges, governs their interactions with other biomolecules.

Early Markers of Cardiac and Skeletal Muscle Metabolic Derangement in the Apc(min/+) Male Mouse. [PDF]

Cancer Rep (Hoboken)
ABSTRACT Background and Aims Cancer cachexia is a metabolic and wasting disease that occurs in up to 80% of cancer patients. Currently, there are no clear diagnostic criteria, its effects are irreversible, and it cannot be treated. Most patients progress undetected to late stages of cancer cachexia, stop responding to traditional treatment, and die ...

Protein O-glycosylation in the Bacteroidota phylum. [PDF]

FEBS Open Bio
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.

Combinatorial Roles of Heparan Sulfate Proteoglycans and Heparan Sulfates in Caenorhabditis elegans Neural Development [PDF]

, 2014
Heparan sulfate proteoglycans (HSPGs) play critical roles in the development and adult physiology of all metazoan organisms. Most of the known molecular interactions of HSPGs are attributed to the structurally highly complex heparan sulfate (HS) glycans.
