Amides of glucuronic, galacturonic, and mannuronic acids
Journal of Research of the National Bureau of Standards, 1948 Heretofore the amides of glucuronic, galacturonic, and mannuronic acid were not known, and methods were not available for their preparation. It has now been found possible to obtain the amides of uronic acids from the corresponding 1-amino-uronamides by selective hydrolysis of the glycosylamino group.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect Science, EarlyView.RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

South African Journal of Science, 2010 A single-source precursor route has been explored by using the diphenylthiourea cadmium complex as the source of cadmium sulphide (CdS) nanoparticles. The reaction was carried out using hexadecylamine (HDA) as the solvent and stabilising agent for the ...

The FEBS Journal, EarlyView.Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Methyl and Benzyl (Ethyl 3,4-di-O-benzyl-2-O-benzoyl-1-thio-β-d-glucopyranosyl)uronate
MolbankMethyl and benzyl (ethyl 3,4-di-O-benzyl-2-O-benzoyl-1-thio-β-D-glucopyranosyl)uronate were synthesised from a protected thioglycoside in three steps. A regioselective ring opening of the benzylidene acetal with BH3.THF generated C6-OH material, which ...

The FEBS Journal, EarlyView.Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.

Journal of Fish Diseases, EarlyView.ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Profiling of Flavonols in Seeds and Sprouts of
Natural Product Communications, 2014 Seeds of Luffa cylindrica (Luffa) have been considered as agricultural wastes. However, we hypothesized that the seeds and its sprouts may provide bioactive components that could provide health benefits for humans.

Glucuronic acid, a precursor of ascorbic acid in Aspergillus niger
, 1957 The isotopic work of Jackel, Mosbach, Burns and King with rats, and that of Sivarama Sastry and Sarma with plants, showed definitely that in both these species, glucose is the direct precursor of L-ascorbic acid.
