Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

Environmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...

Structure-guided function discovery of an NRPS-like glycine betaine reductase for choline biosynthesis in fungi

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Oxidation of choline to glycine betaine is a major pathway for choline degradation and glycine betaine biosynthesis. Although this oxidative process is found in all domains of life, enzymes involved in the reduction of glycine betaine to ...

Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Lifespan-Extending Endogenous Metabolites. [PDF]

Aging Cell
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

Betaine chloride-betaine tetrachloridoferrate(III)

, 2012
The first betaine chloride tetrachloroidoferrate(III) double salt, \((Hbet)_{2}Cl[FeCl_{4}]\) = \((Hbet)Cl·(Hbet)[FeCl_{4}]\), was obtained from a solution of betaine hydrochloride (HbetCl) and \(FeCl_{3}∙6\) \(H_{2}O\) in water. The crystal structure (orthorhombic, \(\it Pbcm\), \(\it a\) = 6.2717(13), \(\it b\) = 12.841(3), \(\it c\) = 25.693(5) Å, \(

Dietary Betaine Improves Intestinal Barrier Function and Ameliorates the Impact of Heat Stress in Multiple Vital Organs as Measured by Evans Blue Dye in Broiler Chickens

Animals, 2019
Simple Summary Heat stress alters the normal physiological status, compromising the function of organs such as the small intestine. However, evidence exists of a wider distribution of organ dysfunction, stemming from factors such as a reduction in blood ...

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Suppression Effects of Betaine-Enriched Spinach on Hyperhomocysteinemia Induced by Guanidinoacetic Acid and Choline Deficiency in Rats

The Scientific World Journal, 2014
Betaine is an important natural component of rich food sources, especially spinach. Rats were fed diets with betaine or spinach powder at the same level of betaine for 10 days to investigate the dose-dependent effects of spinach powder supplementation on
